A friend beat me to a salvage title '90 300D 2.5 black on black tex with working AC and spare long block and transmission was asking $2000 but I know it went for less. I forget the miles but way under 300K or I wouldn't have been interested. My SD's been on Craigslist for almost a month at $1800. A half dozen inquiries, no one's come to see it.

Hopefully these cars still mean something where you are :/
