If there’s one certainty in the Porsche world, it’s that the 911 Turbo models are destined to always be the most desirable. In a trend that’s more predictable than any index fund out there, the turbocharged 911 models have always appreciated to over six figures, provided it has a conventional manual gearbox (the 996 era was the only one where the Tiptronic ‘box was available as an option.) The next best thing? A 911 that looks like a turbo, and built that way by the factory. The 1985 Porsche 911 Cabriolet shown here on eBay sports the desirable M491 option, which gives a naturally-aspirated model a variety of Turbo-specific upgrades.

One of the best features about a 911 Turbo is the flared bodywork. The rear haunches are always significantly wider than the non-turbo cars, and this alone is worth the price of admission. It’s likely why some brilliant engineer and/or marketing agent at Porsche made the call to offer the Turbo’s bodywork to buyers who didn’t have the budget to step up to the grand daddy of 911s. Also, while Porsche did sell a 911 Turbo Cabriolet in this timeframe, it’s exceedingly hard to find and one sold last year at auction for over $156,000. This one has a Buy-It-Now of $94,911, making it downright sensible by comparison.

And even though you didn’t have a turbocharged flat-six sitting out back, you still got the benefit of other available Turbo-model upgrades. These included the suspension, brakes, and seats from the 911 Turbo, and this car has been additionally optioned with a limited-slip differential and a three-spoke sport steering wheel. It’s in marvelous condition inside and out, with the seller noting recent work that includes new fuel and brake lines, and reupholstered seats. There’s also a performance exhaust system and mention of a leather-covered dash, which I can’t tell whether it came from the factory that way or was installed after the fact.

Now, I will say this: the standard engine is going to feel like a bit of a let-down compared to a turbocharged 911, which is the sort of car that will put hair on your knuckles. Featuring a 3.2L flat-six making 207 horsepower and 192 lb.-ft. of torque, it will still offer respectable performance with that unmistakable air-cooled sound. The bodywork is the story here and is what will ultimately sell this 911 Cabriolet; but if you’re almost at the same money for a 930 with some miles on it and perhaps a tattered interior, the question becomes which collectible 911 is the smarter buy?
