I just started running my roadster. Got it for a steal, $3500.00 as a roller, just had to put new 4 link brackets on the rear. I did rewire it though and looking at the add you posted I would say that car would need it also but just my opinion and not the best look at it. Hope it works out for you I know that I really like the one I have. Getting it on and off of an open trailer has been an a little bit of a hassle though. I have to jack up the front of the trailer quite a bit but that's all. Here is my racing junk, not top of the line but I like it. This was a couple of weeks before I finished it. Runs 10.0's with a mild 383.
Here are before and after wiring shots, so you can see why I rewired.
