I purchased the 1.8S Special Edition package, which had a killer stereo system, (in-dash 6-cd changer, 9 speakers (incl sub in the trunk), and the stock cd player. Unfortunately, this was by far the best quality of the car. Within the first 3 weeks of owning the vehicle, the rear strut was replaced & within the first 6 months, the gas tank (& other parts corresponding to the fuel intake) were completely replaced due to a recall. It has also been in the shop at least 4 times since then due to an unaccountable loss of transmission fluid, which has yet to be resolved. MPG has never gotten over 24 city or 28 hwy. I'd say overall somewhat reliable, but needs work on the mfg end of things.
Most certainly the stereo! Awesome sound, conveniently placed cd changer. Also really liked the SE-R body package, real sporty look gives the car a fun vibe. The color of the interior was a real smoothe charcoal grey, which blended well with the black dash and doors.
Suspension could be a lot tigheter, vehicle corners very poorly, even for low end car. Please make more comfortable seats! I drove from San Francisco to Boston and couldn't wait to get out of the car every time I stopped! Move the cupholders too. Mfg could make more reliable parts for this car.
