Peter, it sounds from your comments, that the Three Wheeler is not the car for you and never will be.
That isn't what I said. It is a wonderful car that I'd love to own, but let down by poor attention to detail in finishing it.
On a car built today, or brought to 2014 specification the chassis problem has been sorted, the steering improved to be perfectly good, the compensator sorted and with the right lubrication the bevel box is probably OK.
All it needs is to have the interior better finished using quality fittings and fixtures in some places and it is the car it always should have been.
