You'd probably be surprised how many car parts go by airfreight, it still makes me wonder when I'm carrying airfreight and it includes some hefty bits of car.

There's a good chance prices will go up, even if it's not strictly justified by exchange rates and import duties, it will be a good opportunity for sellers to suck their teeth, rub their chin and mutter 'well, what with brexit sir, you know how it is....'. But then that is also the saving factor, if there's money to be made selling car parts I'm quite confident they'll work out how to get them here and quickly.
