Hello everyone, I am new around these parts and to e30s. I picked up my 91 318is around the beginning of December 2006 and have done all required maintenance to the car and it has since been running excellent. Here is the breakdown of my e30 m42:
Mileage: 184,000
Color: Alpine White II
Wheels: Ronal LS 15"x7.5"
Tires: Kumho Ecsta MX 205/50R15
Interior: new OEM shift knob, replaced lights on dash and fixed ground for fuel gauge, hardwired Valentine One
Exterior: cleaned it, replaced bad low beam, painted light retaining rings satin black in preparation for when I buy Cibie CSRs
Undercar: Magnaflow custom catback exhaust minus resonator, replaced transmission and differential fluids with Redline products, e36 M3 shorter shifter, e30 M3 control arm bushings, new control arms, new tie rods, fuel filter
Engine: took out "hot air intake" and put in original airbox with an afe panel filter, Dinan chip
I have got a couple more things to do on it maintenance-wise before it's in tip-top shape, but as of right now it is running very healthy.
Here's some photos:
