That was the conclusion I came to when I got my truck. Used ones were $20k with over 100k on the odo. My truck was the last '06 on the lot, a base model and I was able to knock the $40k sticker price down to $32k.

Every vehicle I've owned whether bought new or used required a rather large infusion of cash somewhere between 100-130k on the odo.

I could stomach the sting on a used vehicle with 50-60k as I figure I'd get a couple years of use before the sting of a major repair, but with 80k on the clock you could be stung the first year of ownership. If I can get a used vehicle for 1/3-1/4 price of new, then I can stomach a $2-5k repair bill after a few years use. But paying 2/3 the cost of new a major repair bill could get you be into it for the cost of a new vehicle, and still have an old vehicle with no warranty.
