If you can find one of the 29 British cars, a 4.0-litre RS is now worth around £200,000. This is a slight drop from the c.£250,000 they commanded brand new, but still a big jump over the £128,000 list price.
4.0-litre engine a fine swansong for the GT3
Many cars will have found their way to collections now, unlikely to emerge for many years. A GT3 RS 4.0 is a guaranteed investment thanks to its rarity and provenance.
Buy if: Nothing but the ultimate GT3 will do, with its guaranteed future value a bonus.
Don't buy if: There are any kind of budget constraints.
We found: Again, we were out of luck. Should a 4.0 RS come up for sale, it's likely to be in the region of £200,000.
Price Guide -
Ex-Harris owned or not, all 4.0 RS GT3s should be immaculate and command a similar price.
