Pauls spot on, the amount of money now being spent on original race RS500s is huge, come over and take a look

The cars are back in the classic racing spotlight big time and will remain there. The serious big money collectors are now getting involved, where as the RS200 is seen as a bit of a relic with no real race/rally use anymore even though I love them as well.
Race on Sunday, sell on Monday was the old saying. You can jump into a nice cosworth road car and tour at speed around Europe with ease, big boot and 4 comfy seats. I bet they would get just as much attention on the streets of Monte Carlo as the loads of supercars they see everyday. I have only been to London once if mine and the attention was amazing, had one guy in a huge brand new AMG Merc pull alongside us on the M4 past Heathrow, with a big grin on his face, thumbs up and mouthing "straight swap"
A low miles original moonstone RS500 always seems to top the list of cars to own on here, get in quick with Marks one, it might be a long time before another comes up for sale and it will be for a lot more then. As good as money in the bank.
