I currently own a 1992 Mazda 626. The Mazda has been good to me so far. The Mazda has a decent sound system installed. I found a set of wheels for a 96 Mazda 626 that I put on my 626 in a junkyard. I choose 205/50/R15 tires cause I wanted a low profile tire. The car sounds good, but doesn't set off car alarms. =) I'll post more pics of the 626 as I upgrade it.
I installed a new aftermarket cold air filter, battery, and radiator (old one cracked).
