Whenthe 930 was pulled from the North American market due to emission regulations, the aftermarket jumped in and and started turning the 3.2 Carreras into turbo-look cars. The quality of the body work varied greatly and trying to replicate the rest of what the turbo had was very expensive and much more involved.Porsche wisely decided to capitalize on that and in 1984 began offering theM491option on the 3.2 Carrera that remained through 1989. You basically got a factorynormally aspirated Carrera with almost everything the Turbohad, except of course, for the turbo.The M491option package included:The wide-bodyThe turbo whale tailThe turbo wrap-around chin spoilerThe turbo suspensionThe turbo brakes, wheels, and tiresThis option was not an inexpensive one and the prices ranged from about $10,000 to$15,000 during the five year run. This kept production numbers low, making the M491 equipped models both unique and rare.Records show that in 1986 there were 76 coupes, 58 targas, and 226Cabriolets imported into North America.The M491's were highly desirable as track cars with the handling of the Turbo combined with the reliability of the 3.2 engine.This 1986 911 M491 has had a major engine rebuild as well as replacing parts with those that had been changed out over the years, to the correct ones except for the wheels which are "19 Forgelines.You can download the invoice for all of the work done by clicking here.Carfax download available by clicking here.Some of the options on this car are A/C, power windows, mirrors, seats, and sunroof,aftermarket AM/FM CD, new black leather seats with red piping, and limited slip differential.
