My Rx 8 manual, 2004, 35000 miles, beauiful. Should I sell it? How much is it worth? How do I sell it on this forum?

 

I would sell on Bring a trailer. They seem to go for the most on there.

 

Should you sell it: it's 21 years old so it's not going to deprectiate much more. It's probably not worth a lot (maybe 10k with the low mileage? Manual or automatic? Which trim?)) but it will still be worth the same in 2 years. Nobody can tell you to sell it or not, if you need the money, sure... If you don't, maybe keep it in good shape and maybe in the distant future it will gain value as a classic.
