A friend of mine told me about this forum and suggested I respond to this thread. I completed my Locost 7 five years ago and my wife and I have taken a lot of trips around southern Ontario. This summer after adding a detachable trunk box we took a 14 day, 6,000 k/m trip to the east coast and the car ran great. It is all steel construction with a Toyota drive line. The exhaust volume has been further reduced with a second muffler and the side curtains, carpeted interior, and top offer acceptable comfort on longer highway trips. I put together a summary of our trip to hopefully motivate more Seven owners and builders to equip their cars for overnight trips. And I will post it along with some pictures if the group is interested. I realize it is difficult to put on side curtains and to a degree reduce your driving experience. But once you have completed your first 500 k/m highway trip in comfort you will wonder why you ever went without !! Who knows, your wife or girl friend may even go for a spin with you when it is 7 degrees C like my wife does.
Thanks, Vernlocost
