your spoilt for choice!

i think basically any mainstream modern car is available in diesel now days.so its more u think of a car u want and get the diesel version.

as mentioned something prestige like a bmw or the other end something like a golf or mondy.

the misses has a golf Gt Tdi 150bhp, which is plenty quick enough, quicker then the gti 1.8turbo anyway

a exhaust and remap/chip easily sees 200+

better turbo and intercooler etc you can even push 250+

one question tho...why diesel? i have them cos i prefer the driving style and simplicty/strength and the torque you get.

if its for economical reasons, only way you will see a return is if ur a motorway commuter. due to diesel being soooooo expensive now and diesel cars commanding a higher price than petrol cars on purchase (especially on a private sale).
