Generally, in my experience.....
Foreign made cars generally cost a little more, and service costs a little more but you get better overall quality and longevity. Domestically made (American brands) tend to be cheaper here, and their parts are generally cheaper, but lower quality and more prone to breaking. This has become less true as the owners of American brands have diversified, Japanese and European auto manufacturers have built plants here in the US.....but I generally still think my take holds true today.
Everyone has their own "would never buy that" American brands. My dad like to joke about Ford that it stands for "Driver Returns On Fire." Fords are ubiquitous, and affordable but things shit out on them all the time from what I understand.
I've never owned an SUV so I can't comment on brand choices. Except to say that yes, I think Kia is a much better product than when it started. It started suuppppppeeeerrr cheap and janky and I think they've upped their game. You could easily research this.
Dunno what to say about your dad. Fathers are supposed to love protecting their kids, and daughters in particular, from predatory auto purchases. And he's a big car guy? Kinda curious.
As for how they might try to take advantage of you as a girl.....the truth is, they will take advantage of everybody if they can. Women have a reputation for not being good in high pressure sales situations. Whether that's true or not, buying a new car can be pretty tense. It comes down to how well informed you are, what you can see plainly in front of you, what they will prove and whether or not you're willing to walk away.
In the digital age, dealerships have to be a little more careful. If they post a price online and when you get there to look at it it's different, word of stuff like that gets around. People don't want to have their time wasted, and dealeships want to make a sale. They're even willing to "take a hit" in order to make that sale. When in truth, that "hit" is eating into a margin they've already well padded out for themselves. What really makes them the money these days is financing. Selling the car, moving the unit, they'll probably get a commission of some kind on that. But if they get you to finance through them, now you owe them for a while and I imagine those "accounts" are what most salesmen are truly after.
But to back up a step, here's what you should do to establish facts:
-Note the price, mileage, condition, photos, and all details that they publicly advertise.
-Compare what the same kinda car in the same kinda condition with the same mileage of the same year generally goes for elsewhere. Is their price way off that? If it's way high or way low, either there's reason to be suspicious or it's overpriced and just not a good buy.
-Compare these things to what the car actually is at the lot. Is it suspiciously higher? Mileage not stated correctly? Condition a little too generous? Not the actual, exact car they were advertising (this happens FAR more than you'd believe.) If any of these are true, you should start being suspicious.
-Ask them for a vehicle history report. You shouldn't have to pay that. If they want you to buy this car, make them provide it. Carfax or w/e service is good these days. You'll learn if this thing has been in an accident, stolen, salvaged, etc....these things should all effect the price if true.
-If it's got more than 60,000 miles on it, ask if the timing belt has been replaced. If no, then you gotta factor that into the cost of the vehicle because it's coming.
-Ask how long the vehicle has been on the lot. They may well lie, but if it's been there for a year, you know no one is looking at it and that means you can negotiate from a better position. You want to buy this thing they've had a hard time getting rid of.
And then there's just the tactics you gotta be aware of used by salesmen:
-Offering confusing package plans that seem like a good deal but are additive rather than necessary. If they want you to pay anything more than the agreed on price and the taxes, ask why and if you don't like the answer, walk away. "Transportation fees", "clean up fees", "warranty fees", "title and licensing fees" any fee they tack on to the sale price should be questioned and by and large rejected. Some businesses just operate like that and may stick to their guns. But when the charges are bullshit, you'd be amazed how many of them disappear when it means it might cost them the sale.
-Being vague on details. Most things they don't tell you or highlight don't improve the odds you'll buy it. They don't mention those things for a reason. See: accidents, theft, etc...
-Leveraging Fear Of Missing Out to pressure you to make a decision sooner. Either they're getting paid or you're using up their time. ("I've had quite a few people look at this in the last week, it's a nice car.") Could be true, could be bullshit, but it's attempting to pressure you into buying either way.
-Promising they'll take care of anything wrong after you buy the car. If there's something that needs taken care of, should it not already be taken care of when they offer to sell it? Anything they say they'll handle after the sale happens on their dime, on their time. So it either won't get done, take forever to get done, be cheap and/or temporary, and/or have the cost passed on to you. I suppose another option is that it's just done well and good. But I wouldn't bank on it.
And here's just some attitudes I think are helpful when going into spend a lot of money all at once:
-It's your money. Act like that really matters.
-Do your research until you actually feel confident, then act.
-Ask. Questions. Questions formed from your research. If you didn't ask it, they often can't be blamed for not telling it to you.
-Fight for your money. You are the marketplace, these people want YOUR business. Act like your business is important (because it is, to you AND them) and demand it be treated with honesty and respect.
-Appreciate that a "small" car problem today can become a big problem as early as the day after you buy it. Squeaking, rubbing, grinding, humming, wobbling and all manner of jank only gets WORSE. If you notice during a test drive, it's a problem you're agreeing to purchase. Don't buy something with obvious problems, which seems obvious but people often willingly to overlook because they're feeling pressured or they've already convinced themselves to buy it.
-Negotiate. Really you can only negotiate these days when you can make a decent argument why the price they're charging doesn't work for you. Things they didn't do that end up costing you after you buy it as a reason why they should sell it to you for less. That's what all the research and questions are about, is finding those details you can leverage to negotiate the price down if it's warranted. "Oh you haven't replaced the timing belt? That can be anywhere from $500 to $1000 to replace. So let's take that off the price tag." Negotiation isn't for the timid and it doesn't always work. People are somewhat less willing to horse trade than they used to be, but many still will. You just can't be irrational about it. You can't ask for $2000 off a $7000 car and not have a pretty good reason why you think that's "fair."
-Be ready to walk away. That's the most powerful negotiating chip you have. You always have options, you don't have to be married to the first decent car you find that's too expensive, has too much jank or you don't like the terms of.
I'll give you two experiences from buying my last certified pre-owned Toyota.
1. It was almost perfect, except the change container near the steering wheel. The latch was broken and it just flopped around. When I asked them to fix it as part of me buying it, the guy actually did a little eye roll at me. It took them over 3 weeks to get the part that they handed to me. For having a pretty much rock solid low mileage vehicle, the fact they overlooked that and thought I was making a "deal" out of it just never quite sat right with me.
2. While I was sitting at the desk in the dealership negotiating, the guy I was talking to had to get up a minute and go, I think, confer with someone. Anyways, his boss is walking the floor where the other salesmen are sitting. He turns to another salesmen adjacent to where I am, and says loud enough to be heard across the enormous show room floor "Haven't seen any sales from you in quite a while Bill." Then strolls away. The look on Bill's face was one of real hatred. That's why I shit on salesmen so much. Their jobs suck, their bosses suck, they're under pressure to sell sell sell and that can lead to a lot of stuff that eventually comes at your expense. So I advocate for being aggressive with them as per a lot of what I said above. If they want my business they have to work for it AND not be dirt bags.
