Bought an E7 (1999) with a blown engine to help repair mine. I have broken it now, and have a shed load of parts available. Hampshire based, but small things can be brought into London (Tower Bridge - commute is up the A31/A3, off at Raynes Park, up through Wimbledon, Plough Lane, up to Tooting, then up the A24 to Clapham, down to the Wandsworth Road, up to Vauxhall Cross, over to Elephant, up the Old Kent road and then up to Tower Bridge).
Prices are usually about 80% of ebay buy it now prices, unless they are way off the pace. Fair, but I’m not giving them away - I still have my ZZR, and may well get another one at some point, unless they are all so ratted that it isn’t worth it.
