Peter,
Really sorry to hear the news on your horse and hope there is a clinical solution to the problem.
I know exactly the dilemma you are in as I faced it earlier this year and was within an ace of selling the Plus 8 for a new Plus Four as I have a buyer in the wings on here whenever that day comes. I went out for a long drive in the Plus 8 and that was it I just knew I would regret it so have put the idea away for a while at least.
I'm waiting for the electric roof model
Good luck with both situations.
