Considering the EU imports probably 10 times the amount of cars and car parts into the UK than the UK export to the EU, I'd suggest the EU need to tread carefully if they try to shaft us on any deals regarding the Auto industry.
They need to strike a good (fair) deal or it may bite them in the exhaust manifold.
And if the motor manufacturers pull out of the UK, just slap their imports with a massive tariff - I can go without a new car for a year or two while their stock piles up
