If you're thick as shít then avoid like the plague...
Personally i prefer the V8 for a select few reasons..
#1 if even if you maintain it they will not last, camshafts are made of toffee, look after the cooling system especially.
#2 they'll do 17mpg on petrol/Gas with LPG being 50ppl it will do the "equivalent" of mid 30s mpg in your dreams..
#3 They have max torque available by 2400rpm, enough to break the diffs and shag the gearbox
The diesel is more reliable the P38 and uses less fuel subforum is littered with far more Diesel issues than Petrol at the moment because many have run out of cash doing the liners etc on the V8.
Oh and...
Ahem...
"your choice" eh?
