Hi all. I'm the proud owner of a 2002 Protege5 that I bought this June. She's got 160k on the clock, but still feels great. Engine and transmission are in great condition and the car's been well cared for all its life.

I wanted to ask about the best place to get good parts. It seems like there are 2.5 million places to go, so I figured I'd ask the Mazda community.

I currently use the car as a DD, but I would love to also take it to the track and auto cross a few times a year while still using it as a DD. I've been crewing at NASA weekends for a friend for the last few years, so I feel like I have a good idea of what to upgrade/refresh on the car to make it track-worthy. If anyone has suggestions on where to get some good OEM parts as well as some good aftermarket parts, I would love some good suggestions!
