My wife took me down to Pecco's Velos in downtown Ottawa at Christmas time for a really big surprise. She'd ordered a custom hybrid bike for me, first time ever I've had a bike customized for me. Frame w/ carbon fibre front and rear forks and I was able to customize everything else. Bars, seat, seat post, brakes, gears, crank, pedals...everything. I took it out for a ride today and I have no idea how I could've waited so long. It fits perfectly and it's really light.
Not a car, but it's got wheels.
