Another contender, if you want diesel economy without modern hassle of requiring long runs, would be a Rover 75/ MG ZT-T with the BMW diesel
Agree but with a few caveats. I bought a ZT-T after advice in a STW thread. Ran well, handled brilliantly and returned 47mpg. Lovely car. Loads of cool extras like a programmable diesel heater to defrost it in the morning. Constantly had to replace suspension components and cracked 2 18″ alloys. After 3yrs got fed up replacing bits and moved on. A mate has a 75 estate and that has needed fuel pumps replacing. Despite this, they’re decent enough cars.
A4 and Passat attract too much of a premium. C5s are horrid IMO (Had 2 of them – never again) even though I like Citroens in general.
Skoda Octavia TDi is the one to get – with a decent SH, cambelt done and regular oil changes. Most of my Eastern European friends seem to drive them – and they seem to be fairly sensible about where their money goes.
