My dad has a 70 sx supreme convertible. I’ve heard there was somewhere between 795-1000 made. They are pretty under appreciated cars. It hasn’t ran in 15 years. i was lucky enough to drive it as my first car in the early 2000s in high school. He refuses to sell it because he knows it will end up with 24” wheels. It’s been in the family since 1979. It has the 455, th400 dual gate with a 12bolt. Nice to see some people that appreciate them!!

I have never seen an SX with a manual transmission. Was it not available with that package? Just curious.

I believe I’ve seen them but they are not common if they were factory. You don’t see the sx too often as they were kind of the step child to the 442…

Nortell Oldsmobile in Chicago ordered 50 Pink 1971 Cutlass SX cars, some convertibles. They had to order 50 to get them done by Oldsmobile. I've only seen one since visiting their showroom in 1972 where they still had one leftover.

A classmate in HS drove a pink '71 SX.Well actually his Mother did,and so did he once he got his License.That didn't last very long as we all teased him.

That is so funny about your classmate driving the pink SX. My mom wanted to buy the pink/parchment SX convertible, but we shared that car. I said "no way" because I figured the guys would razz the crud out of me. The dealer at Nortell really pushed that car as it was March of '72 and still sitting in the back of the dealership. We got an orange 442 that was ordered by the dealership but wouldn't be in for four more weeks.

That car is somewhat known. Allegedly, according to original owner, the standard rear bumper was a factory installed mistake.

It really is a good story, especially considering the condition of the car.

The rear bumper and emblem are the hallmarks of the car that make it the sleeper and classy car it is.

----I do believe it was a factory mistake, and wouldn't throw away the bumper presently on the car, But (just me) I'd put the trumpets and bumper on.....Bill S

wow, but no rear sway bar, mounting holes are there. I would expect it would come with an SX 455 package
