And they can't go on forever sadly.. for BMW for instance for the 3-Series, before the E21 there was the BMW 2002.. then they "upgraded" to the "E" designation... and for sure one day they will drop it, or just add something to it.. as Peugeot is trying to do, passing from 3 to 4 digits in the future... same goes for Porsche.. at least for the 911... 993, 996, now 997.. they could still launch a 998 and 999. but a 1000 would definitely sound wrong, so they will have to find something.. st-anger, any idea?
