There are a number of companies currently building motorcycle engine powered cars for both street and track applications. Some are complete factory built, finished cars while others are in various stages of completion or kit form.
Depending on your skill level, tools and facilities at your disposal, time, energy and intended application you'll have to narrow down the choices and choose from there. If you're thinking of buying or building one of these beauties, keep in mind, road legal in one country may not be road legal anywhere else, so be sure to check with local registration authorities and with the company producing the car as they may already have the answers you need.
