^^ the high RPM on the highway thing is really only a problem if you are going 75-85. Keep it at 70 and it's nice and quiet.
Also, even with all the engine mods I've done I pulled 36.5mpg on the highway with the windows down for a 350 mile trip.
I've also never heard of the windows rattling.. and I would know, as I ALWAYS have my windows down unless it is raining or too cold. I've also driven the car like 12 hours in a single day a few times without even getting a little bit uncomfortable. Maybe they are uncomfortable for larger people?
The rust spots on the back fenders though, I did have that. It's covered under warranty, the dealership had that area fixed and repainted.
I also have no idea what maxek is talking about his shoe hitting plastic.. maybe he has an automatic and something is different down there I dunno.
I for one think the engine sounds nice stock, and sounds AMAZING with the racing beat catback.
Yeah there's plastic rattles and stuff.. caused by me modding stuff and forgetting to put screws back in properly and such. Plus my car has 73k miles, has an aftermarket (very stiff) front motor mount, is lowered, etc.
They are GREAT little cars though, I never want to let go of mine
