www.mobile.de - 500,000 cars - just type in what you want - try and get one from Germany - they are car mad!!!
Take Cash - do a deal!!
My broker (NU) only wanted the chassis number to insure it - when you buy a car in Germany (for example) the dealer/individual will give you 3 documents (a "breif" and a "shine" - I think they are called)- then you go to a local registration office, get some temp plates while you drive it back.
When you get back, as long as its over 6 months old you pay the DVLA £25 to register it - easy peasy!!!
I have bought 2 cars from Germany - LHD of course - excellent value.
