Have they found a cure for the bearing problem yet?

Believe so - its called procuring a bearing fit for purpose rather than procuring a sub standard/cheap product (aka 5 speeder..) - there were rumours that having a rear hub bearing with grease inside it was an optional extra...

Ref CX recalls - the recalls(?) were all post Covid? And still radiator issues occurring today on the upgraded/repaired plus sixes...

As to sales of Super 3 - or lack of - many months ago one of our clients who is in the EU dealer network suggested that it had been said that the Super 3 was costing more to build than MMC could sell for - which is scary when you consider new Super 3's are currently advertised at dealers already £10k less than launch price....

Ask MMC - I have had a few lengthy conversations with Mark Baldwin at MMC regarding the chassis cracks and associated failures on behalf of clients but he wasn't able to offer a cost effective solution (£15k for a chassis change on a 2013 car is not cost effective) so we had to devise our own chassis upgrade which to be honest makes the front end of the 5 speeder so much more stiff/stronger than even the MMC replacement chassis - all done at less than a third of the MMC price.

Please note that I really do wish MMC to be successful but some of the mistakes still being made at every level are so frustrating to see....
