We’ve recently featured a Saleen S7 – the standard, naturally aspirated version of America’s most outlandish supercar. But what we have here is the more powerful version of Steve Saleen’s Irvine, California-built, gill-riddled, street-legal monster.

This version of the S7 is powered by a twin-turbocharged 7.0-liter Ford V-8 making 750 horsepower. That’s enough power to propel this thing to 60 mph in 2.8 seconds – all the way up to its 248 mph top speed. And it’s a legitimate car – not some thrown-together-in-a-barn sort of thing. They built these between 2005 and 2009 (the original S7 went out of production in 2006).

This car has only been driven about 300 miles since new. A recent service means it’s ready to add to that number, and rapidly. Only 13 Twin Turbo S7s were built in 2006 (and production fell off a cliff after this model year), making this is one of the final S7s built. It’s a true American supercar – and the best version of it. Click here for more info and here for more from RM.

The Costin brothers are probably better well known by the companies they founded than by their names themselves. Mike Costin co-founded Cosworth while brother Frank Costin worked at Lotus and co-founded Marcos before joining Roger Nathan in 1965 to build a prototype race car.

Costin did the chassis and body and Nathan worked on the engine. That engine was a one-liter straight-four tuned to the max, putting out 100 horsepower. The chassis is made of tube-framed steel at both ends with plywood in the middle. The body on this prototype is aluminium (later cars were fiberglass). Now a coupe, it was originally an open-top roadster. This is the original Works prototype racer and was campaigned in period by Roger Nathan.

Nathan did win the 1966 Coupe de Paris in this car before selling it in early 1967 (when it was converted to a coupe). The engine was also replaced at this time and now carries a Twin-Cam Lotus 1.6-liter straight-four. The car is being offered from the estate of the man who bought it in 1967. It raced for a few seasons before being parked and is being offered in as-parked condition. It’s the perfect project car for someone who wants a car that is eligible for many historic races. It should sell for between $36,000-$43,000. Click here for more info and here for more from this sale.

Duesenberg J-386

1933 Duesenberg Model J Convertible Coupe by Bohman & Schwartz

Doesn’t this just look like a classic Hollywood-owned car from the 1930s? It is. It was purchased new by Academy Award-winning actress Marie Dressler and she had a LeBaron Convertible Sedan body fitted to it. She didn’t own it long before it was acquired by producer/director Roy Del Ruth, who took it to Pasadena to have Bohman & Schwartz (the duo that sprang up when Murphy went out of business in 1932) put this awesome body on it.

This is the only Bohman & Schwartz-bodied Convertible Coupe on a LWB Model J chassis. From the side, the car looks gigantic. Most of the LWB cars had big Phaeton bodies on them… not the two-door convertible type. It’s incredibly imposing. It is powered by a 265 horsepower 6.9-liter straight-eight engine.

There are only six LWB Convertible Coupe Model Js in general, making this pretty much one of one (which most Model Js were anyway). Bohman & Schwartz only bodied 14 Duesenbergs and 10 of those 14 consisted of modifying existing coachwork. It has been part of the Harrah Collection, the Blackhawk Collection and has resided in the Imperial Palace Collection as well. It’s a fantastic example of 1930s automotive elegance and excellence.

Porsche 912 Prototype

1965 Porsche 356B/912 Coupe Prototype

Porsche really hasn’t produced that many different models over the years (by name, at least). So imagine trying to restore one and you go out and buy a parts car only to discover that it is one of six original factory prototypes for the car you are restoring. Guess what: you change the focus on the car you are restoring. That’s what happened to the discoverer of this car.

Anyway, the Porsche 911 was introduced to replace the 356 in 1963. Porsche 356 production continued through 1965 and to hedge its bet on the new six-cylinder 911, Porsche introduced the four-cylinder 912 as they phased out the 356. It was basically a 911 body with a 356 engine in it. This car carries an engine from a 1964 model year 356SC. That means it is a 1.6-liter flat-four making 95 horsepower.

The 912 isn’t nearly as collectible as the 911 (and never will be). They are still in the price realm of mere mortals, but they won’t be forever. But what will always be high-priced and collectible are numbers-matching factory prototypes of legendary sports cars. This fits that bill. Only two of these survive, so here’s your chance.

Update: Not sold, high bid of $600,000.
