Gahhh! vBullentin just ate my reply! Second attempt:
It's like selling a BMW 525mx and it's really based on the 300 series.
I see your point, Morgan, although the 5xx series isn't "better" than the 3xx series – just bigger.
It made me think of a odd thing with BMW model naming though:
The formula used to be: first number defining what series (3xx, 5xx, 6xx, 7xx or 8xx). the two following were the cars engine volume in decilitres (316, 318, 320, 325, (328) or 330). Then some bright marketing guy decided to call the 1.8 litre car "316", the 2.0 litre car "318" and the 2.2 litre one "320". The "325" and "330" still use the old formula though. What gives?
