The Pembleton Motor Company started selling a Morgan Trike style cyclecar a few years back. It was very true to the original cyclecars -- small, lightweight, 3 wheels. It's engine and most of the suspension comes from a Citroen 2CV.

This build diary is for the Pembleton Brooklands, the 4 wheeled version of the original Pembleton car, the Grasshopper. It's a very nice website with lots of detail.

Now if only his pages would render nicely in Firefox/Mozilla...
