I've been looking at lemon/buybacks too. Considering some of the prices and knowing that I'd be willing to deal with replacing HPFP I might go for it. By now I would think the 2007's would have had HPFP issues fixed.
I've also been lurking/looking at Donohoo.
QC335 is this your car that you traded in? I was seriously considering selling my car & going to take a look at this exact car. They gave you $19,000 for it? Now it looks like they are trying to sell for $19,000 to get rid of it. Maybe it has been on the lot for too long? Have any issues with the car before you traded it in?
