If the lack of rust checked out, and you are not a purist

, I'd buy this car all day long for $30K. All. Day. Long. Add back the front bumper, throw some black tape under the side fender grills, maybe (maybe not) get rid of the three gauges and aluminum sheet in the radio area and move them up to the speaker hole a la Alpina. Cheap, nit picky things that can be done over time.
Cool to see the M30 motor envelope still being pushed - such a great motor with so much potential. I'd like to know more about this one, especially the crank used, and what it puts out for power. Dyno sheet available? Should be a torque beast. I'd also like to know more about the suspension mods, brakes and chassis and what has been done to strengthen them, especially the brakes.
Or strip it out, strengthen the chassis, throw a cage at it and make it a track day car.
But mostly, I'd drive the crap out of it.
If it were a different color and it checked out rust wise, I'd actually look into selling mine and getting this one.
