She's a highway machine. Silky smooth accelleration. She holds the road like an autobahn purebread. The engine rules, except for those pesky oil journals (nice job designer guys). When the miles start to rack up, the strangest things start to go out on it. Air coditioner wierdness, transmission gremlins (limp home mode?!) leave you and the dealership scratching your head as to what's wrong (computer diagnostics?!). The heaviness of the car eats suspension and brake parts. On a positive note, if you can find a mechanic who can identify and fix the little strange things that will happen to this car, it will last forever!
Engine and suspension.
Engineer the parts on the machine to last as long as the engine.
