645 vs. 650 Reliability

I have been looking at past post and I seem to think the 645 is more prone to problems than a 650. My thought are that because the 645 was the beginning of the current gen. it had it's kinks that had to be worked out thus the 650 turning out with less problems. Anyone else think the same? So far my 08 650 has been running great .

I think they both have thier own issues. But like other vehicles as the next generation comes out they find ways to improve it.

70k miles still running strong on my 645. Its my daily driver and I haven't had any major issues with it that's cost me more then a couple hundred bucks. A few little ones here and there but it's expected I guess. The warranty really hasn't even been used yet..... Except for the Window modulator.

You are one of the lucky ones!
