you have gotta love them to run them, my caddy which ive got at the moment, is 7.7 litres and returning 12mpg if your lucky, had it down 8mpg.
but the way you look at it is, you get cheap insurance, also tax exempt so your saving a couple of hundred quid already, plus i only use them for weekends,
the water pump has just gone on the cadillac, and its £70 for a new 1, all the way from the US. funny thing is its £20 for the part and £50 for shipping.
