Wasn't it posted here that one of the Super 3's production delays was due to BB/Belt whine in the demonstrators, and that MMC was resolving this before new customer cars were built? I know that there were 5-Speeder owners that were hopeful that some of this 'fix' could then be applied to their 3-wheelers.
I'd also be curious to see the quality of the welds in the delivered Super 3s, since that was another 'those poor welds are because it's a prototype" comment?
