Picked up the car ~a month ago now (wow time flies).
Just recently found out how rare these cars were (~27000 ever built) - very close to the m3 (~15000 or so built) compared to the normal 325i (couple hundred thousand, pretty sure)
The '88 4-door is even more rare, in that they were only ever imported to canada (not the US). Pretty sure that there were only about 350 '88 4-doors brought over. Thats pretty freakin uncommon. If anyone knows better figures, please feel free to correct me.
Anyways; current mods:
Smoked sidemarkers (one didnt turn out so good
H&R front, e30m3 rear springs on Koni yellow top-adjustable shocks
(i know its a bit of a ricerish list, but i have no $$ to do more intense work, yet)
MarkD 91 or 93oct chip, e36m3 injectors, m30 afm + cone filter
