I visited both dealerships yesterday for a drive test and I ended up choosing the X5 over MDX. I fortunately found one on their very huge lot that fits the specs and options I need, so I was able to bring home my new X5 on the same day. I chose the V6 engine because it is less expensive and I don't need the too much power of a V8, yes the V8 is quicker and has bigger/wider tires and chrome kidney grilles, but that's about it.

In opposite to the reviews and forums I read about these 2 vehicles, I did not expect that the X5 gives a smoother ride, very comfy and quiet. I found the MDX not braking well, but it accelerates faster than the X5, but it really felt like an upgraded Pilot for me. Visibility is better in the X5. The side mirrors and the far back windows are bigger.

Some reviews and forums said the interior is too plain in the X5, but I loved the interior! It looks more luxurious! I loved the idrive that controls the whole lot on the X5. The MDX is like a fighter jet, it has one hundred buttons, you have to press different buttons for a/c, navigation and audio (of course anybody will get used to it later) and there is no split screen like the X5 where you can have navigation on and music displayed at the same time in an 8.5" lcd.

One thing I noticed when I sat in the MDX is how hard and uncomfortable the driver’s seat is. It has roomy interior than the X5 though

I'm not really sure if I like the exterior of the MDX, it is very futuristic. I can't quite figure out if it's actually the design that I can get used to, it is like an autobot. For me, the X5 is better looking than the MDX inside and out (and that is only my own opinion).

For me, both are great vehicles and perform very similarly. I agree that MDX is more reliable and more powerful, but I believe that some people will get lucky with their X5 and some will be unlucky with their MDX, there are no guarantees. Each vehicle has their strong points, but the overall differences between the two are minor except the price tag. A loaded MDX will cost far less than a loaded X5, and that might be an issue for those who consider both vehicles. Again, the X5 is pricier, but (I believe) it worth it. Other than that it looks better for me and the X5 has always have the edge in terms of prestige because of the BMW badge it carries.

I am very happy with my decision and I really enjoy driving this ultimate driving machine but I must also admit that it bring more worries because of the reliability issue, I hope I won't regret it!

Can someone teach me how to post pictures? When I hit insert image I am being asked for a url of the image being attached, I am not even allowed to post attachment, thanks!
