Are there other sources of auto classifieds to use when searching for used motors? Do all the traders use it? If not where else should I be looking? I am potentially looking at Audi A4 A6 and 5 series Bimmas. If I cant outdo my bro's 02 M5 then a well loved 540i (2000-2004) would suit me down to the ground . Will have a budget of about £8-10k in 6 weeks time. Also will have the struggle of selling my 11 yr old 328i coupe to deal with .
