I have a 1990 Mustang
LX with over $9,000 invested including flat tops, Cobra intake, ported 2:01, 11 1/2 compression, 2 1/2" custom headers and exhaust (all stainless), o/s throttle body, Crower cam, new high-end plugs, wires, cap and rotor. New 3:83 rear posi, lowered 2" with high comp rear suspension, Centerforce clutch, new rubber and brakes all the way around, fiberglass cowel-induction hood, chrome Centerline rims. Have never run anything but synthetic oil and all the best parts. This car is my baby and has been treated as such, nobody has even so much as sat in the drivers seat in the last three years but me. Very tight car with low mileage and runs like a top (never seen snow and is straight and cancer free).
The only reason I'm getting rid of it is because I need a pickup and I'm not sure what a reasonable price to ask would be, so fire away.
