The 1970 Oldsmobile Cutlass Supreme SX is definitely a car that hides its light under a bushel. Under that unassuming exterior beats a heart of pure muscle, and while it might not have been the toughest car on the block in 1970, it certainly wasn’t a car that was put to shame, either. This Cutlass Supreme SX is a clean car that is looking for a new home. It is located in Chatfield, Minnesota, and is listed for sale here on eBay. The BIN for the Oldsmobile has been set at $18,000, but if you are keen, you could always try your luck by making an offer.

The owner purchased the Cutlass back in 2004, and it has had very limited use over the past 15-years. He says that it has undergone a repaint at some point in its original color. He claims that this is Aztec Brown, but the paint doesn’t look dark enough to be that shade. He does say that there is some minor bubbling under the paint and that this could be filler. The car certainly appears to be solid, and apart from a dusting of surface corrosion, the underside of the car appears to be solid. The rockers, along with the lower fenders and lower quarter panels look remarkably clean, so this looks like a car that could be driven and enjoyed as it is.

There’s a little bit to do inside the Olds, but there appears to be nothing urgent. The biggest job will be to replace the headliner, as this does have a number of tears in it. However, this could be undertaken at any time. The wheel isn’t original, and nor is the radio. There are a set of aftermarket speakers fitted into the rear parcel tray, but otherwise, the interior looks to be original. The upholstered surfaces are in great condition, and the rear seat doesn’t look like it has ever been used. The Cutlass is also fitted with factory air conditioning, but this is currently inoperative.

When compared to the rest of the car, the presentation under the hood isn’t as good as I expected. This can be forgiven because it is here that we see what the Cutlass Supreme SX package was all about. What you got for your money was the L33, 455ci V8, producing 320hp. Shifting duties were undertaken by a 3-speed Turbo Hydramatic transmission. You also received power steering and power brakes as part of the deal. The SX package was designed by Oldsmobile to allow potential owners to buy a car with respectable performance, but not have to face the crippling insurance costs that went hand-in-hand with owning a true muscle car. An SX could cover the ¼ mile in a neat 15 seconds, could accelerate from 0-60mph in 6.9 seconds, and reach a top speed of 129mph. All of this in an unassuming looking package. Since purchasing the Cutlass 15-years-ago, the owner has only managed to accumulate around 300 miles in the car, so it definitely hasn’t been worn out. The worst issue with the car at present is a leaking seal in the transmission. The owner does say that the buyer could drive the car home, but if they try this, then they will need a decent supply of transmission fluid. He suggests that the best option would be to take it home on a trailer and attend to the leak before driving it any distance. On the plus side, he does say that the mighty 445 is nice and strong.

The 1970 Cutlass Supreme has been described as “a 442 in a suit,” which is a pretty fair description. It is one of the great hidden gems of the muscle car world, and good ones are becoming harder to find. This particular car looks like a solid example, and it also looks like it would be quite a rewarding project car. With nice examples selling for prices in excess of $30,000, this is a project car that appears to be well worth the asking price.
