I strongly recommend you to ask for a 300Tdi engine and
not a Td5, it's much more simple, drinks less fuel, no ECU
and all that for only 9 BHP less.
You will be able to get ROW specifications. I got myself
a 2005 D90 with 300Tdi engine, no ECU, no ABS, no
power windows, no central locking... just A/C.
You will probably have to wait about 4 months for
delivering, so you can plan quietly all modifications
you want to do.
