I'm not a huge fan of the kit but I know there are a lot of people who enjoy seeing it.
I found this one on tradecarview for a pretty reasonable $26,000 considering a few factors outside of having an original RB bodykit.
For starters it seems to have had a rebuild as there are photos of the engine being removed. It has an incredibly expensive and rare exhaust made by RE Amemiya, a stock engine and 50,000km. It's actually quite funny to see an FD with a rocket bunny kit and a standard engine and interior. I'm going to make an assumption here and say the previous owner had a built, ported big single turbo engine in previously and was concerned about the resale value with it in. I don't know I may be wrong?
Anyway here's a bunch of photos of the RB RX7 FD.
