At this point: the quality improvements made over time, to the automotive fleet as a whole, dwarf any deltas between brands from a given year.
Also, the supply chain has been so homogenized at this point that underlying components are nearly identical.
Their ad men work really hard to convince you otherwise, but if you really think brand X is going to sell you a 25 thousand dollar car that will burst into flames months after you drive it off the lot, while brand Y, for the same amount of money, can build you a magic car that will go 300k miles without seeing the mechanic, you are just silly...
It just doesn't work that way[br][br]I have one small commuter car, a corolla, and one larger family car, one of the new Chevrolet Impalas. I bought both because I like them and felt like I was getting a fairly good deal (relatively, car dealers being the scumbags that they are) on each.
