We've seen some spectacular BMW restomods over the years, from a 135i-based 2002 convertible to a gorgeous E30 M3 that is modified in the same vein as the Porsches reimagined by Singer. BMW restomods are beautiful when done right, and Robert Downey Jr.'s 3.0 CS is another prime example. That car has M5 power, in the form of the S38 engine from the E34, and today's restomod is similar, except that it's something altogether new. This is the Oletha, created by Smit Vehicle Engineering. It too is M-powered, but it's the V8 from the E92 M3 GTS. But ignore the powerplant for a second and just take in those gorgeous curves.

SVE doesn't explicitly say what its Oletha is based on, but anyone with more than a passing interest in BMWs can tell you it's a Z4 styled to look something like a hardtop Z8, one of the most beautiful cars that Munich has ever produced and one of the entrants on our list of the greatest roadsters ever. Oletha is described by the company as "the car we wish BMW had built - an uncompromised synthesis of BMW's greatest design, engineering, and racing achievements."

It's said to be based on German engineering and infused with American ingenuity and passion, and that is evident from the grocery list. Under the hood is the S65B44 we mentioned earlier, a 4.4-liter V8 here producing in excess of 450 horsepower with an 8,500-rpm redline. Adding to its drama is a set of individual throttle bodies, a custom carbon fiber intake manifold, and a custom exhaust made from stainless steel and Inconel. A six-speed manual and a mechanical limited-slip differential ensure that you don't miss out on any fun when behind the wheel.

SVE has also retained hydraulic steering while adding KW adjustable suspension, lightweight forged aluminum control arms, AP Racing upgraded brakes, forged monoblock wheels, and Michelin Pilot Sport 4S tires. That gorgeous body is made from a carbon composite, resulting in a curb weight of around 3,090 pounds. Another nice touch is the electronically actuated rear spoiler, while the cabin (of which we have no images) features the "highest quality materials" and a high-power sound system. Seats are a choice of eight-way adjustable touring units or composite sport seats. SVE says that there's extensive use of 3D printing here, so we hope that these aren't too pricey, but any car with custom bodywork is likely to put a big dent in your wallet. We think it's worth it though, and would love to take one for a drive on our favorite canyon roads.
