1970 Oldsmobile Cutlass Supreme SX W32

 

As of February 9, 2010 we have 479 cars in the SX455 Registry 

 

 

Most muscle car experts will agree that Oldsmobile reached its pinnacle in 1970, the same year Olds introduced a notchback intermediate called the Cutlass Supreme.

In 1970 and 1971 this new Oldsmobile was available with a special option called the Y-79 Performance Package and the car was named the Cutlass Supreme XX. The SX featured several 455ci engine options, a 400 Turbo Hydra-matic transmission, a cut out rear bumper showcasing the dual exhaust, and other goodies not found on a standard Cutlass Supreme.

Sophisticated styling, luxury options and great performance create the ultimate gentleman's muscle car!

  

Classic collectors are familiar with the Hurst/Olds, 4-4-2, Rallye 350, and the W-Machines like the W-30 and W-31. But in 1970 there was also a very special W-Machine called the SX W-32. The SX W-32 is an Olds 4-4-2 in a Cutlass Supreme body and only 1,025 SX W-32 Holiday Coupes and Convertibles were produced.

 

The Cutlass Supreme SX is certainly the "undiscovered" GM muscle car. The production numbers for this two-year-only (1970 & 1971) model are less than half of the highly collectable Olds 4-4-2. Plus many of the SX cars were sent to the junk yard crusher before the rarity of the car became known.

 

By design, ALL Cutlass Supremes had the same basic VIN codes, so identifying a Cutlass SX is difficult to an untrained eye, and "clones" are starting to find their way into the collector car marketplace by unscrupulous sellers.
