I used to have an MK3 unfortunately sold it.
To the hairdressers commentators (who drop bikes

) I would suggest you try hold on while drifting....
The MK1's can be had for cheap but you need to check for rust all over the place and in particular the arches. Also I seem to recall an issue with a pump? Best google it though.
Other than that if they have been looked after the engine will go FOREVER!!!
