Located a 08 AW from out of town. Has Premium and Tech package. No PDC or Winter Package. 14K miles on it - CF roof. Not CPOed.. But buying it from a BMW Dealership. They said they could CPO the car which would cost me an extra 3500.00 ... It only has 14K miles and 2 years left of existing warranty. My questions is do I CPO it and only get 2 more years after my warranty - or wait until my 2 years are almost up and just get an aftermarket warranty from BMW for 3500.00 then but it would add like 3 to 4 years more? Thoughts? I'm buying this car tomorrow so any help appreciated!!
