> Audi (example): letter (car/SUV/race car)+ number (quality: 1-cheap, 8-luxury) - BMW: first number is a quality class, two numbers is the Engine size. - Mercedes: first letter is a quality class, number is the engine. You need to already know the brand to know this. > (quality: 1-cheap, 8-luxury) How high does it go? If they decide to turn it up to 11 tomorrow, is 8 still "luxury"? I can't agree that this sort of versioning is any more transparent. > (e.g. The Audi r8 and the a3, the 90k speakers and the 1k set) This means nothing unless you already know the brand. There's going to be a minimum set of knowledge required to understand these versioning schemes.
