Everything BMW puts out might be reliable but that doesn't mean it's more reliable than the tried and true. You can spin it any way you want but the more parts involved and the more electronics involved the more chance for breakdowns. Most of you have mulitple cars and live next to a dealership or good shop so I guess it matters not. A few of us don't and I wish the engineers sometimes would just slow down and not try and outdo everybody and just continue to refine products. Of course then they probably wouldn't sell any. Ha!! Give me the old dipstick and non runflats and less electronics but the public is clamoring for more. I swore I wouldn't buy an E 70 after I put 200,000 on two E 53's but I did!!
