Yeah aside from the factory lightweights there was no kit or other race options.

Verify the bonnet is the original factory part and not a modern reproduction. That affects value.

Verify #'s match, it was pretty common to find a replacement motor or transmission versus repairing the original -OR- many 'upgraded' the 3.8 cars with the newer motor or fully-syncro gearbox. The data plate is next to the air cleaner.

Check for rust at the floor pans, wheel arches, battery box, door bottoms, and rear suspension where the arms bolt into the body.

Check electronics carefully, even small idiosyncrasies can be a hassle to fix.

Motors are robust and fairly inexpensive to rebuild. They are not as unreliable as many would believe. Overheating is probably the biggest downfall, but plenty of options to rectify the cooling system. Swapping out the two bladed fan goes a long way just by itself.

Brakes on the early S1 cars have about half the stopping power of a modern vehicle, which you have to be conscious of 100% of the time while driving in traffic. Likewise because they are not slow either. You can be tolling down the highway in 4th gear, roll the throttle on, and pass the car next to you like it's standing still.

Good luck- post pics if he buys it.
