depends on the normal terrain you drive on, does it justify a 4x4 etc?
the thing with having a discovery etc.. no 3rd party parts as a friend discovered and they weren't cheap.
a friend had a "karioke" as I call em.. again , not the cheapest car to run here. think tyres were £250 a time.
I'd really look into the parts cost before buying also.
UK cars are different from the US ones, due to the terrain, although locally there is a humvee, which looks even bigger on the roads here.
