Superb car, My 02 530d Sport was Manual and returned 45+mpg even after being remapped, superb performance from a silky smooth ultra refined 6 pot engine - I would have another in a flash if I wasn't looking for an M5
As it happens, my old E39 Diesel is for sale on Pistonheads -
http://www.pistonheads.com/sales/786520.htm - the seller is the bloke who bought it off me - he has made a twat of it with the M badges tho, but they are easily removed

- Unless he has made a cunt of it elsewhere aswell, then that car wants for absolutely nothing - it is in perfect condition and I rekkon he would take 6k if you waved the cash under his hooter aswell
Edited to add, standard the car is 193bhp and 280 lb/ft - with a remap at Evolution Chips (Stu) - 230bhp and 380 lb/ft torque and more mpg
