I don't believe this would have happened on Peter Morgan's watch he was a man of great integrity.
Richard with respect that is a very subjective opinion and in my case not based on fact. My first Plus 8 was delivered as an Export Order and I dealt with Peter Morgan and Derek Day direct. My car was specced with a full alumium body at extra cost and the paint on half the car stripped off within 6-months of owning the car as the etch coat had not been applied to the full vehicle. After protracted negotiations with the afore mentioned individuals I paid for the car to be resprayed, allegedly at a reduced rate, but still a major expense on what should have been a warranty item.
I went on to buy two more new Plus 8’s in 1984 and 1986, and sold all three at a small profit on the purchase price (those halcyon days!), but the quality of all three was really sub-standard even compared to other manufacturers at that time and PM was not really interested in customer complaints or genuine warranty issues.
The worst car quality-wise that I have ever had from Morgan was my Series I Aero delivered in 2002, I still have a copy of the letter that I wrote to CM detailing a list of over 50-items that needed attention. Not too much interest then either, plus ça change - I have continued buying Morgan’s fully aware that they do not have the development budgets of say a Porsche or a Mazda (for their MX5), but I remain satisfied that I have been fairly treated by the company in more recent times and thus I continue to buy Morgan’s, including an early M3W!
