If they hold off until things are perfect, they will lose sales as people lose interest and move to other things. If they send out flawed products, they will lose sales at present and will lose future sales to people who might otherwise buy another Morgan.
You summarise the dilemma well.
I suspect that, in markets where the dealer network is strong, MMC will pull off the trick of squeezing between this particular rock and neighbouring hard place. I don't know what the internal financial agreements are between dealers and MMC on post-delivery remedial work, but I do know that all three cars I have bought have had issues - what made the difference between a miserable and an acceptable experience was the patient fault-finding efforts of SGT and BHM. I know from this forum there are other great dealers out there as well.
Personally, i'm not convinced that the larger 'plate glass' type dealerships that MMC are now appointing in the UK will have the same service ethos with customers or tolerance towards MMC... There may be trouble ahead?
