On the goo instructions you inflate then immediately drive 5 - 7 miles to seal.
Auto gearbox locks if you lose total electrical power as I understand it so don’t see how battery would help if no electrics.

On the Aero auto the gear selector can only be moved with the ignition on and a foot on the brake.
Another joy, if the electrics pack up with the key in the ignition you cannot remove the key as again, the car must be in Park to remove the key.
So, with no battery power the car is immobile.

So basically the car is stuck on the side of the road with the key in the ignition waiting for a thief with his own tow truck to take it and put a new battery in.

I remember parking an automatic car on a steep slope and couldn't get the key out as for some reason it thought it was not in park even when I pushed up on the gear lever to try make it was certainly as far into park as it could get. Ended up driving 3 miles and then walking back just trying to find a parking spot not on such a slope. I was tempted to park in the same spot facing downhill but the police in that area are very strict about not parking facing the wrong way and would very likely have booked me. Just another one of the reasons all my cars are manual and will be until I have to replace them with electric.

Picked up my Plus Four in September, no jack, aerosol, hammer and centre wheel nut spanner. I have Alloys!
Bought a scissor jack and modified the top contact plate to ‘flat’ added rubber packing.
I don’t like the aerosol as you loose the tyre regardless.

I've used a product similar to this to repair a tyre:

https://www.autoseal.co.uk/about-2/

but it is designed to be installed before you have a problem. I believe it can be washed out later if required.

I also have autoseal in my Supersport but be aware it can cause front wheel balance..

The large volume +4SS tyres required 375 ml per tyre..but had to reduce fronts to 325ml to bring back into balance.

As Jon says it can be washed out easily if required

Capta2 - I also have alloys and have decided to purchase a scissors jack and modify as you have. I e mailed the factory and, to be fair, got a prompt reply(!) which gave short shift and said that “they decided not to supply a jack with the CX cars”.They said they would revisit the situation and come up with a more coherent solution- but no jack was forthcoming!

Cheers!

I can only say that I wish I had known this before I decided to swap my Roadster in for a Plus Four. Like others I have paid a lot of money for a spare wheel and now find I won't have the tools to change it in the event of a puncture. Having had a classic Plus 4 and Roadster I, foolishly it now appears, assumed there would be the storage place under the rear shelf with the tools including a jack in it. I've had Morgans for seven years and have covered nearly 50,000 miles in them in that time which acrtually is only really six years due to Covid. How do I now continue to do that sort of mileage here and sur le continent without the means to change a wheel? How are you guys planning to overcome this issue. And BTW did MMC really say there's nowhere to put a jack so we don't provide one?

I don't understand the issue regarding regarding lack of Neutral on this gearbox at all. My wife now has her second BMW with this gearbox and it has Neutral. How come the Plus Four doesn't?

Could you get a small scissor jack, wrap it in something and tuck it under the spare wheel maybe? As the car is so light you might be able to find a really small one.

But you're right, for MMC to design and sell a car that can't carry the means of changing a wheel shows just how out of touch they are with people who like to drive long distances.
