I think the chassis is immaterial - if it works better then fine - I hope there is still a bit of ash around to creak and that they still produce a manual gearbox. I`m sticking with my 4/4 sport now until too decrepit to drive it - and then apparently steel chassis cars will become very desirable (and sell for a good price).
MMC have to look to the future or go under and it is the iconic Morgan shape that many of us love and that, hopefully, will be retained.
