E70 X5M - It's the CHEAPEST BMW ///M Car for a Reason

Ever thought about buying one of these BIG twin turbo V8's ? They are excellent cars when properly maintained but could be a money pit if neglected. Why the E70 X5M is soo cheap and what should you look for if buying one. This is my ultra reliable X5M I bought about 2 years ago with 160k kms - I dropped the engine on the very next day after buying it and did a full rebuild also servicing the transmission, differentials and everything else considered to be an issue in these cars and the result was just as I expected, very good.
