However, many Saabs reach 300,000 to 400,000, so 110,000 and running fine is not saying much. Just my opinion, letting the engine idle for 30 seconds to 1 minute also allows the driver time to close the sunroof and windows. The sound of an idling Classic exhaust echos nicely in a concrete parking garage :-)
