 I love how the car is smooth for the most part. Slower acceleration than some cars, then again it isn't a sports car nor is the road a race track! It keeps up with fast highway traffic -140 max and on the one way roads it is small enough to squeeze on the side when passing other cars as opposed to most cars. Engine can be a bit noisy at times, but it is def. not loud when driving at high speeds like a lot of other cars, including luxury cars, like those buzzing sounds. In all fairness to this car, which I read a lot of minor or just plain stupid comments about, the car is an amazing one for the price, performance, and overall quality! (*It also depends on the driver and how s/he drives & car).
