When I was working for Rolls-Royce in Palm Springs, I would leave the 300SD idling with the A/C on all day long so it would be cooled off when I needed to run errands, and occasionally, take clients home. They loved riding in the old 300SD and remarked on how cold the A/C was.

That car would idle for 8 hours a day (never over 175°F) and use less than 1/4 tank on the gauge...

People always said it was bad for the engine and I would laugh when I thought how we used to leave or 4.6 Crown Vic's and Mustang's idling 8 hours a day for 300,000 miles and then we gave them to Public Works and they are still running... :-)
