All good advice Peter, except Ken is thinking of changing his Plus 8 for a roadster.....
I would have no problem converting My +8 Bitsa to a +6 Bitsa. But the "Market Value" would not equal the cost of modification. Or even come close. The advantage IMO would be nil. I have driven a 2005 Roadster. I have also driven a 2000 Bog Standard +8. Being a DIY sort I like My +8 Bitsa. At the moment looking for Cow Hide for the interior that looks like a Cow. Starting to look for a Tanner that can do the job for Me. After all I live in the U.S. Northwest. I want a Morgan that looks like I live in the West. No I am not going to mount cow horns on the bonnet.
