a true story from one of my customers.
He owns a foreign car repair shop. Customer brought in an early 80's Volvo 240 for wiring harness replacement (a rat ate it). He had Volvo parked in the shop and then a 90's S500 Mercedes came in for service (plugs, filters...etc.) so he parked the Benz in the shop near the Volvo.......
He opens shop next day and finds the entire Mercedes driver's seat eaten away...foam, leather...all of it.
