carmax covered my car under their maxcare EW. I have the driver window go bad and the fuel sending unit.
They told me if they couldn't repair any of those themselves, they would send me to infiniti dealer.
fuel : they used another g35 on their lot and exchanged it. (i can only assume)
window: dont know if it was used or not, but I picked my car back up from them and it was fixed.
a year later, sold the car back to them.
All in all... a wasted 1600 or what ever it was... cant remember. cause if you add up all those repairs, it wont even equal to that if I did them myself.... ( which is highly capable of with the help of this forum ) found this forum after I bought the car....
