I do not do a lot of journalism any more but one thing I would like to do is a feature comparing the 3 Wheeler and the 4/4 from the point of view of owners. As Paul Jacobs has mentioned, there are quite a few who have made the switch.
I first thought about the idea in the middle of last year when I retrieved my M3W from Toulouse after the crankshaft-pulley bolt incident. I went for a drive in a Plus 4 that Marcassus had for sale and thought it rather nice - and that the 4/4 might be even nicer as well as more affordable.
