I've always wanted one but never had the guts to get one.
They seem to have got their act together and sorted out much of the reliability issues with them now though. Have a word with Dave Belsten as he used to run one I think as a team driver so he'd have the best input..
If you are in 2 minds about what car to get just try and blag as many goes on peoples cars at club until you find one that suits your driving..
Give me a shout on friday and you can have a few laps with the 502..
