After several years of thorough enjoyment, it has come time to part with my Locost. I have driven the car very little this year. The Midwest Gathering in Onalaska was the one main event. I have come to realize that I enjoy the building part more than the driving part. I recently got back into the boating scene and I am also rebuilding a Cushman 3 wheeler. Too many interests/projects with too little time.
Simply stated, it is a rotary powered, book chassis, with a hinged hardtop. It is ready to drive away. The car became legal on Feb 14, 2011 and is currently titled and registered in Illinois as a 1960 Lotus Custom under the “custom vehicle” category. It is exempt from emission testing in Illinois. I have driven it about 6K miles since “new”. I have driven this car to many Midwest Gatherings. I would not hesitate to drive it anywhere today.
My complete build log is here if you have time to read: viewtopic.php?f=35&t=4145
Finished build pics are here: viewtopic.php?f=33&t=14598
I built this car with the help of this group so I will post it here before listing other places. Price is $9450 .
I will also offer my custom built trailer for an additional price to the buyer. Of course, it too is titled and ready to go.
