Trying to decide - GLE vs. BMW X5 and which GLE engine
I guess your username says it all.

You definitely didn't confuse me - what you said makes perfect sense. I appreciate your insightful reply. I have owned BMWs for many years and had been previously tempted to go with a Mercedes but have usually avoided the temptation, since I thought "nothing drives like a BMW", even after driving the various Mercedes. It comes down to what you're used to. In this go-round I have considered some other SUVs, but have narrowed it to the BMW and Mercedes. One of the reasons to go with the X5 is they do offer the 50i which has an 8-cylinder engine, which I am most used to, while the similar class Mercedes (ML400 or GLE400) has a bi-turbo V6. Yet, BMW in recent years has experienced some very serious problems in some of their engines which is worth thinking about. Also, I don't like the fact that the back seat doesn't go down perfectly flat, which is an important feature for me. The Mercedes seat does go down all the way.
So, yes, I am used to the feel, handling, and throttle response of the BMW, but that said, it may be time to buy a Mercedes, and get used to a somewhat different driving experience. I may need to go for the more powerful 400 engine, even though it is a 6-cylinder, just to get that extra acceleration that I'm used to.
I still need to look into if ordering is an option, or if it's past the cutoff date. So that means I'll need to look at what's available at dealers in a 2015 or 2016, or currently or scheduled to be at the at the VPC.
So having owned both brands, I wouldnt ever go back to BMW. Their cars ride stiffer, I like comfort and that is where MB excels. The major drawback with BMW is with their interiors, just plain boring IMO.
Your original post - "I have actually driven all 4 and have my own early opinions".
I guess your post here is to put your "early" personal opinions aside - and ask for balanced input.
Well... do the Google .. the BMW N63 V8 "probably" is the worst V8 engine to come from any German manufacturer - ever.
Do the Google yourself - and the 4th generation N63 for 2016 I am told by my BMW will only be available for 2016 in the "new" 750 - and NOT in the SUV.
Frankly - comparing "issues" on the W166 in this forum - against the "issues" posted on BMW forum - heck N63 problems posted on a general Google search - BMW V8 be d*mned, nonsensical, and BMW hasn't been able to make than engine design "drive right" in 3 generations over 8 yrs.
It's your call - make sure you put that N63 card table when you wrap up your "decision".
