Same shell stripped and built up again, there is 0 difference between factory cars and conversions. RUF CTR is a ground up nut and bolt model.
Because there were about 55 original CTRs built, its history - 29 factory cars and 25 conversions, all using Carrera 3.2s as a base. No technical differences between the 15 cars with a RUF VIN and the 40 cars with a Porsche VIN. Half of the original CTRs had Porsche VINs, they ran out of blank shells!

Though I realize this is an older thread, I love this thread. I have a RUF BTR III that sustained some flood damage exactly 20 years ago. What I learned from this thread is about my R50-50 6 speed ratios. I didn’t know what they were, even though I tried to find out through much research.
My car only had 8000 km on it when it went into the drink. I salvaged the tranny early on within weeks, draining it of all water and gear oil, filled with new gear oil and spun.
Despite any former analysis on the thread, having researched a bit too, I would argue that any car RUF built from the ground up is a real RUF regardless of the vin POR vs WOR. Obviously, the WOR will command a premium, but that doesn’t detract from all their cars being real RUF cars, quite to the contrary. I only mean cars that were built from the ground up in the factory in Germany.
I noticed that the 6 speed on this thread is 0070? Mine is 0081. I would be interested to know if there is still a possibility for my car to be a real RUF again. All that is missing is the motor HA! The rest I was able to strip out and preserve 20 years ago, and it is a Yellowbird color, though cab and 964 Turbo body on an 89 3.2 ROW Carrera base.
