Well, I have only had my 2-dr.ESi for a few months now, but I drive in excess of 500 kms a day, and I have not had a problem yet. Even at these high gas prices, I am not shelling out my paycheque for gas! Other than the road noise, i find this little puddle jumper to be everything you want it to be. The only other thing is the placement of the drink holders, right in front of the ashtray, so you cant use the ashtray when you have even one drink there! But if you don't smoke then this is of no concern! loL!
Probably the simplicity of the car, nothing is power other than steering and mirrors.
I'd say just sound proofing the car better to cut down on the road noise.
