I read recently that a manual transmission is the best anti-theft device you can have. I had my oil changed at a JiffyLube a while back. No one there could drive my vehicle (370Z) in or out of the bay. Had to do it myself, a violation of their safty rules.
One the cretins there was going into his spiel
offering a transmission flush for $99
I told him “Idiot -its a manual tranmission.....”
Good Lord, you should never let Jiffy Lube touch your car.
