'68 C3 Vette. It had just gone through a very meticulous mechanical restoration by a good friend of mine. Was as close to stock as possible. A lovely little 327 / 350 horse (gross) torque monster and just the right gearing to snap your neck back hard.
Every aspect except the power-train was horrid. Just absolutely horrid. Didn't turn, didn't stop, didn't handle. I didn't feel safe pushing it over about 65 mph
