Hello MH, you are thinking of Hyundai, the parent company of Kia for 5 years warranty.
There are quite a few examples of cars being made in four and two wheel drive, pickups being quite common. There are also cars that look like they should be four wheel drives but are not, the Talbot Rancho being the pick of that particular bunch. If however offroading is intimated at, even just for advertising purposes, then you should reasonably expect to use the car off-road. More important, how does the dealer know where and when any excessive wear occurred? I'm sure Norwich Union wouldn't insure for offroading, NU are not alone where that is concerned, the only way of insuring a car would be through a specialist insurance policy and I doubt that would cover much anyway. Green lanes, as Clive points out, although they may get a little rough, are still classified as roads. At the end of the day, you pay your money and take your chance, glad I did, and the fun was great.
Best Regards
