Gillet

There are "mainstream" exotics like the ones from Porsche, Ferrari and Lamborghini. There are niche supercars from companies like a Spyker or Koenigsegg. Then there's the Gillet Vertigo.

One of the most bizarre sportscars on the market, the Gillet Vertigo is also one of the lightest and quickest on the road. The previous version of the Belgian exotic made by former racing driver Tony Gillet packed a 350-horsepower 3.0-liter V6 sourced from Alfa Romeo. Modest enough, but with a curb weight of only 990 kg (2,182 lbs), the Gillet Vertigo was capable of accelerating from 0-100 km/h (62 mph) in a scant 3.26 seconds.

The new Gillet Vertigo, however, packs a far more powerful 420-horsepower 4.2-liter Maserati V8, promising to give the unique exotic even more extreme performance. We wouldn't be surprised if it dipped below the 3-second mark. No official word on pricing either – each one is made to order and can be just about infinitely customized – but for reference, the previous Gillet V6 model cost around $265,000.
