Should i run ads for car services?

Yeah Google ads work but watch out for competitor click fraud, it is brutal in the auto repair niche. @Carbatterynz made a good point about emergency services, but for those you should run call-only campaigns instead of sending them to a landing page. If someone is stuck on the road they just want to click and call right away... they wont wait for a slow page to load. Also set up tight schedule targeting so you arent paying for clicks when the shop is closed and @nobody is there to pick up the phone. Otherwise you just burn cash.

yes car services can work well with google ads and i would start with search ads targeting high intent keywords and focus on local areas and track calls and also leads to see what works best.
