A good friend is selling a Caterham 7 Roadsport. It's rather nice, although at just over £10k it's probably beyond the budget of most BX owners - certainly beyond me! I've driven it a bit in the last couple of weeks and it's a incredible car. Limited edition, the last of the 1.4 Roadsports, highly specced.
