I know how you feel, but its make or break and you would be gutted if you sold it.

I had the same decision with mine a few years ago, i spent just under 6 grand on new erngine turbo brakes etc etc, thinkin that once it was done that would be it, trouble free motoring for a few years.....No chance the bellend specialist who fitted the patrs left a bolt in the inlet manifold which caused no end of damage... So ive started again

so frustrating but its a love thing
