They have bmw engines till 2000 then they have that crap td5 engine that sounds like a tank is rolling up the road.
get the bmw one as it is a sweet little diesel and once chipped ( 300 quid ) will match the 4 ltr for power and speed.
I own a 98 dse with a power chip and a alard intercooler fitted. ( 205 bhp)rolling road tested.
