I bought my 2001 Eclipse gt at the beginning of summer and ive loved it all. it has a body kit, k and n cold air intake, stage 2 clutch custom paint tinted windows subs and an invadia exhaust system with bigger piping from the cat to the muffler. I love driving the car around and it gets good gas mileage especially with the cold air. Insurance on them is a little high but it is a sports car. in the end if you plan on having some fun with the car and adding on some things its great and i say go for it.
The car could really use some better materials inside. I've also heard of the factory paint being bad, i bought mine with custom paint on it, but i have heard a lot of complaints. store it indoors.
