Although General Motors won't admit, a mid-engined Chevrolet Corvette is coming. Chances are the C8 will debut this January at Detroit, so it's possible the teaser campaign will get underway sometime in the fall. In the meantime, we're left with the occasional spy video and set of spy shots showing what's clearly a mid-engined high-performance sports car (supercar?) being tested.

Most recently, a C8 test mule was spotted being benchmarked against the current C7 ZR1, just to give you an idea as to what level of performance we can expect. However, it turns out the C8 isn't the first mid-engined Corvette.

And no, we're not talking about the various mid-engined concepts GM built years ago. Corvette Blogger, via RaceCarsDirect.com, has uncovered something rather extraordinary that's also up for sale. This is a 1993 Innotech mid-engine Corvette, nicknamed Mysterro, and it's a one-of-a-kind. It was designed and engineered by Design Kral back in 1992. What's 'Design Kral'?

Vaclav Kral was a Czech car designer who also worked for Porsche at various times during his career. He died in 2006, but his hand-built, one-off mid-engined Corvette is considered the best car design of his career. The car debuted in October 1994 at a car show in Slovakia, but is it a real Corvette?

It has Corvette C4 parts such as suspension components, steering column, and braking system, as well as a 300-hp 5.7-liter V8 connected to a custom-built five-speed manual transmission. Customized bodywork includes a unique windshield and – get this – no roof. It's strictly a two-seater but does offer two luggage compartments big enough to accommodate golf clubs. The rest of the interior features a carbon fiber dashboard, leather upholstery, Recaro seats, Momo steering wheel and shift knob, and an Alpine audio system.

Nearly a quarter century after its construction, it has only 62 miles on its odometer. The listing also specifically states the car is in "very good original condition," which isn't a surprise considering the mileage. Included in the sale are original tech drawings, build photos and full documentation. And speaking of sales, how much does this pre-C8 mid-engine Corvette cost? The asking price is 250,000 Euros, or about $292,280 USD. Oh, and you'll have to arrange shipping from its current home in the UK.
