Plus you can request a Car Fax and it will give you the service history, which should certainly indicate any recurring issues. Buying gently used cars from dealerships is getting less and less risky here in the US with the new laws about disclosing accident history and new resources such as Car Fax. Plus checking comparative prices is much easier as well. You can literally do it from your phone now. I feel much more comfortable negotiating now than I did 11 years ago when I bought my last car, which was an also gently used (500 miles) Saturn.
I know a lot of people find buying a car very stressful but it really isn't if you use your head and don't let the process intimidate you. One of the things I do is make them bring the cars to me. It saves me the whole dealership experience where the buyer is generally at a disadvantage and also lets them know I'm no pushover. This is particularly important for me as a woman. I wish it wasn't, but the world hasn't changed quite that much yet. Getting there though.
It goes like this. I pick up the phone and say something like: "Hi, my name is Jeannie and I need to buy a new or gently used car. I've done some research and the Hyuandai Genesis Coupe made my short list. I'd love to drive one but I have limited time. Would it be possible for you to bring a car to me at my office?"
No one ever ever said no.
I'd take the car out over lunch. If I liked it, I'd either call my husband and have him swing by the office to take it out, or take it home so he could drive it that evening. When we were done, we'd call the dealership and have them pick it back up. Worked like a charm and I ended up getting a very good deal on a car I still like to drive 2 1/2 years later.
BTW - The Genesis Coupe was waaaay a fun car to drive. In fact it was too fun, which is why I didn't get it. I still feel a little pang when I see one on the road. They offered me a super deal on one from the current model year that had been returned after 5300 miles because the owner wanted to upgrade to a more powerful version.
