Well, I am officially "old" I guess...I would opt for the convertible too...top goes up when it rains, and in case of a "critter" (bug) swarm...For the price he paid to do that he could for 1/2 the price just buy a convertable car.
Why not just hook up two Goldwings? Twice the horsepower, four seats, and it would be cheaper. Along the same lines as the P-51 to the P-82:I saw one of those at Wings Over the Smokies last year! As far as cost, when I asked the vendor he said first ya buy the bike for say,, $20,000, the trike rear end for about $12,000, and then you have the front end kit installed for about another $12,000,,, Say about $44,000,,,, before sales tax!!! :shock::shock:
Here`s link:Not sure if you guys saw this there was a combination, sidcar unit made by EML a Dutch company and that had 4 wheels, the two normal bike wheels and 2 on the chair.
