My red roadster was PERFECT, had 13,351 miles on it and I paid over $17,000 for it. A wonderful car, 5 years old back then, and in showroom condition.

THen... I wanted a stick, so:

I looked at two XF' roadsters before I bought my Graphite. They both had high (over 100,000) miles on them. Both ran good, but cosmetically were awful, but both were around $10,000.

My Graphite had 45,000 and was, cosmetically, above average - and I bought it for $12,000 from a private seller in Arizona. I flew out, bought it, and drove it home.
As soon as I got home, the ignition key froze (glad it didn't do it on the trip home!) - I had it towed home and drove the Red one for a few days - when I had time, I fixed the Graphite myself. The previous owner had no idea of the stick key nightmare and only got lucky it didn't do it to him!

I think that you are targeting cars that have had poor maintenance. If you want a car that has been LOVED and CARED for, do your shopping here, on the forum. What do you want? Coupe? Roadster? Auto or Stick? Tell us what you want and look in our ads - prices here may be a BIT higher than a dealer - or maybe not, since there is no dealer middle-man. I found mine on Autotradter and had a forum member in AZ go loook it over and drive it for me. (It was TOTALLY worth the $1,000 to fly out there and drive it home!)

If a dealer is trying to selll you an hi-miles car, their business model STILL says they must make money on it. If someone HERE wants or HAS to sell, deal with them direct - they get a higher dollar for their car, you get their car for less than at a dealer, and you get a car that was loved and cared for. Also, we can help with those little problems that come up (bad CPS, sticky ignition key, starting and engine problems with the RCM, problems with putting the top up or down, etc.) These cars can be expensive to maintain if you take them to dealers! (The sticky key fix is $400 to $1200 at a dealer, I fixed mine in 1 1/2 hours in my garage for no $)

Part of what makes the $40,000 Crossfire a car you can buy for $12,000 is avoidable with this forum. This is not a car to buy if you take all of your problems to the dealer!
(not really what you asked about, I know....)
