I'm actually really good with cars too, plus my step brother is the service manager at a local dealership, and he'll put any used car up on the rack for me and have a few mechanics poke around it, for the price of a breakfast pizza, lol.
BUT, I also think it's better to buy a new car now, because used car prices are so inflated.
I have actually only bought 1 brand new car in my life, and I hated it. A base model ACCORD. The car I drive now was a theft recovery vehicle out of Philly that I got a killer deal on....a fully loaded Accord.
I was a used car dealer and have it in my blood. Even now that I can afford any new car, as I said, I am too frugal to buy one unless I really, really love it.
