I was wondering if it's neccessary to let your car idle for a few mintes before shutting it down after driving hard. Or is it that as long as your temperature gauge isn't exceeding say.....100 C, then it's safe to shut down. Does hits practice prolong the life of the engine? Any input would be greatly appreciated.
Also, Do any of you guys know of a wrecking yard for Mercedes Benz in the Bay Area? ( SF, Oakland, or San Jose)
