I seen this 2004 BLACK BMW 645ci convertable (fully loaded,sat nav etc) in a showroom today, 11 000km. I'm considering trading in my 2003 Silver Mercedes-Benz CLK32 AMG convertable with 25 000km (fully loaded, sat nav etc) on it... The BMW is about $34k more, but in beautiful condition... what do you think? shall I trade it or stay with my Merc? The BMW is faster, the Merc has more prestige...tough choice, need opinions! :-\
