Nothing.
This car has amazing reliability. I can wake up in the morning knowing the car will always start. I have not had one thing wrong with it. The car is sporty, it handles awesome, accelerates, the manual makes it much more fun.
It is cheap to operate. The only money I spend on it is gas and oil.
For the price you cannot beat the mustang.
Please post again one month after your warratny expires. I'd REALLY like to know your opinin at that point. I said the same things you said after 2 years of ownership. It's the end of year 3 and the beginning of year 4 that'll get you slanted.
My transition went out twice. My rocker pannel fell off (a plastic bold was apparently never attached at the factory, the panel was just painted on to the car).
