My girlfriend drove a 2002 Mercedes SUV for a couple years. In addition to getting abysmal gas mileage, every time she took the thing in to the dealership to be serviced, the cost was never less than $500, whether anything had been malfunctioning or not.
One day she got to the dealership to drop it off late and all the Mercedes loaner cars had been issued, so they handed her the keys to a Toyota.
She found she was driving a vehicle notorious for its dependability and hassle-free low-maintenance which cost half the price of her Mercedes and wouldn't be so much like a temperamental Teutonic filly. She sold her Mercedes and is now on to driving her second Prius, for which she has nothing but praise.
