My mate has a 4x4 on a H plate with 176,000 miles on it, never been rebuilt so far, one new turbo and a sump gasket, few other minor bits, and it dont smoke, full history mind, by himself, as most cossys get regular if not more oil changes than required by ford service standards..... its definately how you look after them, oh and he knows its never been rebuilt as his dad bought it new and he has had for the last three years....
