2008 BMW X5 SUV 3.0si 4dr SUV AWD (3.0L 6cyl 6A)
Worst Car I have owned 
 I have had X5 for about 1.10 years now put at about 30K miles(Normal family use mostly on Highway).
First I have to say this is a drivers car. Fun stops right about here.
Already I have spend $6000 on it. $3000 for random repair and $3000 for regular service at a BMW shop. Cost to own does not even have gallons and gallons of Gas I have put in it yet. City MPG about 12/13 mpg and about 18/19 mpg on highway. A combine score of 15/16 mpg. So doing the math cost to own this car is 7481.25 + $6000 = $13481.25 (lol). Mistake of my life I have to say.
I have heard that they have made this better in 2014, I guess I will never know :)....
