calling all 91 formula L98's
I just wanted to see how many 91 formulas w/L98 were here. If you want tell a little about your car i.e. color, t-top or not, wheels, mods, and miles.

there you can search by year, model, engine, etc etc etc...
Be sure to search by formula, and formula 350 because technically in 91-92 there was only a Formula with the L98 being optional.
