You have a point, when a car is at an engineering zenith, theres hardly much leeway to make it "better". Only movement left is lateral.
Mine is simply that the engine and gearbox are being loaded into a classic Merc (can't wait for the reaction in the Merc forums!).
The seats also have a chance ofngoingnin, but its a coupe. I could just slide the seats forward to allow entry, but a proper tilt and slide would be more in keeping.
