I bought my 2015 VIP from CarMax, not too worried about not having the CPO as i feel the car is put together well and i have not read about too many issues. so far put on 5k miles and no issues at all
the only thing I have just noticed at CarMax is a slight uptick in the costs for the 15 K900 - i see one there now, 2015 Lux, 4k miles for 32K, but no VIP
I paid the same for my 2015 7k miles, but mine has VIP
