I readily concede to some of these points especially those regarding reliability.
I looked at the four wheelers some years ago. I walked into the show room turned on my heals and walked straight out again. The fit and finish was a shock.
However I always wanted a three wheeler and took the plunge to buy a secondhand 2012 . Had all the big issues also. Funnily enough the finish apart from the chassis and seats is better than the four wheelers I think. Of course all the parts are bought in. Fingers crossed the major reliability issues are behind us
