See the inventor's name? BMW didn't design this, built it under license. Renzo Rivolta was the principal of ISO, the italian company that built the ISO Rivolta (ego is not a dirty word), a glorious Bertone coupe with up to seven litres of Chev that would push it to 170-180 mph.
The correct spelling is Urkel. Its hard to say if that blueprint is the same that Steve drives.. Because I remember the headlight is way up near to the mirror. As compared to blueprint which show near the front axis/tires.
