Bought the car new in 2007 for commuting to replace a Camaro. Si is quick enough to commute and move easily in all kinds of traffic. It gives me average 23 mpg even when I drive it hard. Car is reliable, fun, and not so thirsty. Back seat space isn't that great for adults, but don't mind since I use it to commute. I will be repainting the whole car since the paint isn't that great. After 80k car has been reliable and looks like it will go for another 10 years.
Reliability, responsive engine, interior design and space, small enough to fit most places.
Clear coat on roof, sun visor's quality, and 3rd gear issue if it hasn't been fixed yet.
