I bought my first Viper two weeks ago. It's a 1995, last 300 side exhaust edition, red (the only color I would have), and a low 800 miles. Top and curtains have never been on it and all documentation, wrappers, stickers are in ziplock bags. The collector thought it would be worth a ton of money due to the 300 side exhaust stamping but he realized he would die before it appreciated over the 60K sticker. It looks like I just picked it up from the dealer.
I paid upper 40's but got a car that I'm confident in. I can have repairs just like anyone but I think I did the right thing by paying 4 or 5K more now and maybe avoiding some. It was also exactly what I wanted and I fell in love with it.
By the way, I have driven it every day where rain wasn't a risk. It now has 1300 miles. I haven't slept most nights and go look in the garage a few times a night even though it is under a cover.
