Modern Performance Racing is also an excellent source for Neon parts. The owner has an emerald green Neon (like mine
) with body kit, wheels, custom spoiler, etc. and I believe he also has an NYG Neon with turbo and other mods.
Modern Performance caters mostly to Neons...they do stuff for imports and other Dodge cars, but you'll notice there are lots of goodies dedicated to the Neon.
Nissan - as for your question on the Neon's reliability....they are by no means engineered well like a Volkswagen or BMW, but if you take care of it and take care of problems when they do come up you should be fine. One thing I have noticed with mine..I had some sensors go bad (it has 130K miles so that's expected) and when just one stupid sensor goes bad it makes it seem like the car is taking a major dump. The most common sensor to go bad is the O2 sensor. You should be fine as long as you stay on top of things and keep the car maintained. My Neon is 4 yrs old with 130K miles. It's had its problems here n there and even has had a front end collision, but it is still tooling along fine.
