i have a 2005 manual mini cooper. yesterday i stopped at a gas station and went inside. when i came back and tried to start the car, nothing happened! all of my lights and power windows work. even after i took the key out of the ignition, the speedometer would still light up. i had to tow it back to the dealership so they can look at it.. its very frustrating because i just bought this car 3 days ago (used). has anyone had this problem before or have the slightest idea of what caused it?? thanks.
