Audi TT 180 Quatro. Bi Fuel petrol/ LPG
It has all the usual Audi refinements, 4WD, alloy wheels, heated seats etc and most importantly has a gas conversion which means
(depending on how much you pay for your LPG ) it returns the cash equivalent of 50 to 70 mpg with no loss of performance because it is turbo charged !
It will need a cam belt soon, so is sensibly priced
