It's just my opinion that it makes a lot more sense for anybody who knows their way around a car to buy privately.
For one, the vehicles are cheaper when bought privately. Two, you can save an absolute fortune on ongoing service and maintenance costs because you do all the work yourself and aren't tied to any extortionate dealership arrangements. Three, so what if it doesn't have a warranty, it it breaks down refer to two!
My own situation is as follows. I haven't bought a car for years, I drive a company vehicle. The servicing, repairing and fuelling of my vehicle is all taken care of, I just drive it. I am very very lucky. If I didn't have that company vehicle and I had to buy my own then I'd be stumped. I know nothing about cars and I would probably fall into the category of people who go to a dealership, and get my pants pulled down regarding the reasons you speak of. And it would drive me nuts!
That is why I can't understand why you are even entertaining going to a dealership, when you know enough about vehicles to buy privately and save yourself a fortune. That is the point I was making.
