I purchased a mint SRT-6 Graphite Roadster with 25,000 miles. Literately looked like it came off the assembly line. I gave up on these cars increasing in value and don't really care about putting a car under a car cover just so it sits there and slowly rots away in the off-chance I make a few dollars on it in 10-20+ years.
Bought this car to enjoy it, to put the top down and take it for spins, modify it, work on it and all-around just have fun.
Drive it daily and have 50,000 miles on it now and couldn't be more happy. Love this car and the good memories I have had with it will always outweigh any "investment" this might turn into down the road. Just my 2 cents.
