i was wondering about a good place to get bmw performance parts for a 1993 automatic 325i 4 door sedan such as intake, exhaust, supercharger, throttle body, shocks, springs, rims, and tires. i also want to know about body enhancements such as front bumpers / front lips, , side markers, sideskirts, and a spoiler. last but not least, ive read the car manual twice and wondered if there was anything that goes wrong with this particular car. does anything break down quickly? does anything need to be changed periodically besides the obvious? oh yea, we need the car to remain street / emissions legal. thanks in advance
