i have a 1998 freelander diesel bought a year ago and have had really bad luck with it, goes through new tyres in a couple of months so had the prop taken off making it 2wd, bushes, links, oil leaks, water leaks inside car and now the garage think it needs a head gasket done as water is dissapering somewhere but not on the ground, i has discoverys before this but they are too big and thirsty, have spent £2000 on bits and bobs in the time ive had the car, i use it for towing horse trailers and general driving, at some horse shows on wet ground the 4x4 is needed, what should i do should i upgrade to the 2003 onwards or keep spending money on this? how can i make it 4x4 without wearing tyres? or should i change to a different model? help please
