Something to keep in mind. A tow truck to your trusted mechanic is cheaper than having a $600 part replaced only to find out it did not solve your problem. Additionally might I point out the danger of leaving a 140 Chassis S600 parked anywhere disabled and unattended. The car is worth much more in parts than it is a whole car. They get about $500 a piece for used double paned side glass. Not to mention why someone might want your "full leather" interior. Call a tow. In the grand scheme of things its really cheap. Additionally AAA will give you 100 miles of free towing on a service call.
