I've owned my 1992 Cadillac Allante for eleven years. Overall it has been a delight. It is a very shopisticated car, even today, and has features that most cars never did, like mulitplex wiring, which allows all of the lamps in the car to be monitored for proper operation. Its biggest drawback is the Bosch anti-lock braking system. The 1993 model had a simpler system. Though an excellent system overall, it is very expensive to repair. The car is still a "head turner.: Its Pinninfarina styling is truly timeless.
The overall sophistication of the car's electronics and mechanicals.
