Kashish 0 Report post Posted October 26, 2020 (edited) Hey Everyone, It’s my first time posting here, I am looking to purchase a slightly used 6seriesGC later this year (2-3 months) anyway, I have been looking and test driving both the 640i and the 650i, and my biggest concern is reliability. Some people told me the 6 cylinder engine in the 640i is really reliable, that the 8 cylinder in the 650i is basically crap and that I would be in the shop all the time with it and This concerned me somewhat because I was leaning to the larger engine for my purchase. What year should i go for? And after purchasing it, want some mods (more power) on it so whichone should go for? Thanks ?
