I'm considering a 1997 white/auto/loaded 840Ci with 79K on the speedometer for a daily driver. My research so far shows that it is a reliable car with performance similar to a 540I. Does anyone have any experience with the 840 and would you recommend it? Also, I know that 97 was the last year for the 840/850. Does anyone have the final production numbers and, in your opinion is this a BMW that may have some eventual collector appeal and value?
