Another perspective...
After 2 years with Aldermog, the Roadster I was hooked by the look and style of the car, and found a welcome home in the Morgan communities. But the "vintage charm" soon wore off. I spent quite a lot on suspension upgrades and other alterations, including applying heat/sound proof pads to most of the inside of the cockpit. But it still wasn't right, Caroline found driving it difficult due to the heavy, long throw clutch and heavy steering at slow speed.
So, we bought Tarka the Plus 8: that was in 2014 and since then I've not found anything that could tempt me to change.
BUT.. had the "New Plus Four" been available in 2012 when we bought the Roadster we would have bought one: it looks like a traditional Morgan, probably drives better than the Plus 8 based on my Plus Six experience yet underneath it is a modern car. Not everyone is as in love with the traditional Morgan experience as many are here, the number of very low milage Morgans about shows that they often don't live up to the owners dream. I predict that the Plus Four will change that dynamic and new owners will hang on to their cars. It may seem to be an heretical suggestion, but in a year or so the value of low mileage used Plus 4s may soften.
As has been said, this car is a game changer for MMC. The possible arrival of a 185 bhp Four/Four in 2022 will only speed up the evolution of Morgan.
When I ordered the Plus 4 in late 2011 I was actually intending to buy a Roadster but the 3.0 litre version had just been discontinued and I felt that the proposed, but not yet available, replacement was too powerful for the trads chassis and had more power than I wanted. I tried very hard to get them to build me a car with the Plus 4 SS engine but Morgan would not build it with an easyup hood or in LH drive.
The rest is history and, like Peter, the "vintage charm" soon wore off. I have spent quite a bit of cash in improving the suspension and mild engine tuning. I still think that around 200 hp and good torque is the "sweet spot" for a Morgan sports car.
Certainly if the CX PlusFour had been available in 2012 I too would have bought one. Now, however, I would be discouraged by the price. I would not get sufficient return on the sale or part-ex of the Plus 4 to make it a viable option and I can't really see the benefit to me of changing to a car that is not really how I would like it to be: too powerful and too much torque for such a light car without traction control, and I am left somewhat nonplussed by the lack of a radio. I also feel that they could have done a little more work on the design to get rid of the "pram hood" effect. There have been a wealth of soft top cars that seem to be able to conceal the hood when down.
I am sure Morgan will have a great success with the car but I don't think it is for me.
If they did bring out a 185 hp version that could be more interesting to me as the torque from a turbocharged engine would put it more into my perceived "sweet spot". The only problem with that is that the years are passing for me and I feel less inclined every day to put money into expensive cars.
