Hi planet looking for feed back?

I am considering one of the Can-Am Spyder 3 wheelers as an alternative to a heavy 2 wheeler that I currently ride, and would appreciate any thoughts and observations from those of you who ride one of these. Re handling, comfort on long journeys, typical MPG, servicing costs, I have always serviced my own bikes for over 40 years so how practical is it to service the Can Am.Plus any thing else you would like to tell me. Thanks in anticipation, Andy Pandy. UK.
