My thanks to Dan at Krazy Horse for the loan of the car.
This is a very fast competent modern car that looks like a trad.
I drove the manual version and enjoyed it immensely but to keep the turbo on song you have to stir the petrol with the gear lever. Sixth at 60 or even 70 struggles if you accelerate hard & is really an overdrive. Dan tells me the autobox keeps the car on song as does driving in lower gears in the manual. On the video at roughly 12 min 27 secs I tried some 0 to 60 runs. I would say 5 seconds in non sports mode based upon counting elephants.

You can sense it has less power that then Plus Six but in reality it has loads to spare. It has more power than my S1 Roadster which felt under powered when I got back into it. But it has I would say similar power to a 3.7l Roadster though with the turbo it delivers differently.
In normal gearbox mode the exhaust is pretty quiet, press the sports mode button and the car responds more rapidly and on the over run there are addictive pops & bangs.

It has a start button which I also like.

So a very good if not indeed a great car from MMC. The one I drove is roughly £68k. The build quality was excellent.
Whilst the car is wider than a trad there are no door pockets to store stuff. The glove box has a bulge into it so is very small. Behind the seats is a reasonable space. At 5 ft 11in I needed to move the seat forward.
I didn't see anywhere to put tools & I am not sure if there is a tool tray in the back. Sorry I only thought of that after the event. As you can from the photos there is no space under the bonnet.
The gearbox tunnel is quite hard as it isn't covered in leather. I normally lean my leg against it but in the Plus Four that wasn't comfortable. Though I expect I would get used to it.
Definitely different to a trad but a very very good car. I need to talk to :swmbo and have long think.
