Why Not Just Do What I Have Done For 38 Years, Find A Spot Under The Car Where The Local Grease Monkey Won't See It On The Hoist, And Hide A Duplicate Key.... Cheers Glen.
Gee Glen, I am so sorry that you have to drive a Camry while your car is being fixed but at least it is not the end of the world....oh wait, maybe this is another sign of the end of the world is approaching.
PLUS-when you get your Benz back,it'll already have greasy seats without you having to 'spank your monkey' as you drive it,Glen!
Well my car already doesn't start in quite the normal way, which I need to fix..... I leave the key in the ignition. With all it's quirks, few people could start it, and being a stardard, fewer could drive it. And driving it has quirks too. And it the thief tries to floor it and dump the clutch, they wouldn't make it out of the parking lot, because it has about one dump left in it. Not that I plan on stealing anyone's car, but I think being able to start various cars, of the type that don't need a special computer or something, is probably a good idea.
Well if the planet gets bitch slapped by a Mass Solar Ejection, knowing how to fix older carburetor based engines/cars will be a valuable skill. All the modern cars with computer controlled everything will be multi-ton paperweights.
