I have bee told by three Infiniti dealerships that if I buy a used I30 from any other dealership, and it still has someof the basic warranty left on it, I can purchase an extended warranty from them. It would cost $2,000 and would cover me for 48 months or 48,000 miles, bumper to bumper, with no deductable. Did anyone else buy that coverage? If so, were there any loopholes or problems with getting service done under that warranty? I would like to hear both good and bad experiences.
