Depending on your expertise level and interest, usually you buy a car with the impression that it has already been assembled. However, for those with the proper motivation and the finances to support it, GM is offering Chevrolet Corvette buyers the option to build the car’s engine themselves.

To the tune of $5,800, a consumer can purchase the “Engine Build Experience” option on Corvette Z06 and ZR1 cars, two top-of-the-line versions of the Corvette with engines typically hand-assembled at a plant in Wixom, Michigan, near GM’s headquarters in Detroit. Those who chose this option are invited to Wixom to assemble their very own engine under the supervision of trained GM techs. This also includes the addition of a personalized nameplate attachment to the engine, which is then sent to Bowling Green where the rest of the car sits waiting for complete assembly.

“In a way, this is a dream program for a Corvette customer. I would have jumped at the chance to build the 427 in my ‘67 ‘vette, and that didn’t have half of what goes into one of these modern precision engines,” said Tom Stephens, GM vice chairman for global product operations, in an announcement.

Any car fan would drool over the roughly $70,000 Z06 with its 505 horsepower, 7.0 liter, V8 engine. But then again, why not go for truly impressive power with the $110,000 ZR1, possessing a 638 horsepower, 6.2 liter, V8 engine? Despite being built by those less than professionally trained, these engines still get the perks of a 5-year, 100 grand mile warranty.

Those who choose to make their way to Wixom are still responsible for their own travel expenses, but GM does provide a concierge capable of arranging lodging and meals while in the area. For any car fanatic, the experience is well worth the cost.
