I have an 01 red/black no stripes ACR with just a tad under 500 miles on the clock and its bone stock
would'nt sell it for less than 70K still has DC warranty too not even trying to sell it and had an offer of 69K (cause I told him 70k was my price IF I even wanted to sell, which I don't) from the guy who bought the one below..
01 red/black w/silver stripes ACR 3000 on the clock, bone stock, extra wheels and shocks sold for 59K no warranty left with this one.
So, 50 for the o.p. car is in the ball park if not right there, imo. But don't forget no abs so if you do track with little to no experience out there you most likely will lock em up.
