I love the car but wish the cup holders were bigger. This seems like a petty complaint, but other designers manage to work it in. Also, I wish I did not have to "pop" the gasoline door. With 12,000 miles I still have not had an oil change although I've tried to schedule it twice. I was told both times to wait until I get closer to 20,000 miles.
Give it a larger cup holder, and a fuel fill that works with door lock. If the car is locked I can't refuel. If it is unlocked, it will open. (Like my Audi)
