 This car besides me putting a new engine, because of past engine overheating problems has been running very well. I've noticed shaking when reach speeds from 80-90 but could be just my car... But very fun to drive, but you must realize this is a Hyundai which used to be one of the cheapest cars on the road. So far with this car Hyundai put good thoughts in my head about their cars besides the low performance pick up. But I would recomend a cold air intake to at least get the car moving faster than a turtle.. Has a lot of potential tho, just didn't start off with it.
