I will tell you that its not a car thats been in the spot light like a honda civic or accord but I've seen a few that have been done up very nice. Plus there is a good bit of after market stuff around from body kits to vortek super chargers. Check out
www.cardomain.com in the malibu section. You will see a lot of just spec cars but you will see some blown out ones. most of the people there will post the parts that they used.
