I bought this car at used with 35000 miles on it in 2014. This is the best used car that I'd ever drive. I owned quite a few luxury cars. X5 35d is the most pleasure for me to drive in road with great milage and power.
I have owned my 2010 BMW X5 35d for 10 months and like the car more now than ever. The car is a pleasure to drive and gets very good mileage (about 29 mpg highway for me) for a large vehicle. The low-end torque of the diesel makes it a fun and safe car to drive. Some people like to hate iDrive, but in 2010 BMW fixed the main issue by adding buttons so that many features can be accessed in one step rather than navigating through menus. This is an amazingly clean diesel. Hold your hand behind the exhaust for a while. There is no soot or smell. Great for driving family and dogs around town and on long trips.
The 2010 BMW X5 35d (Diesel) has many advantages and very few disadvantages over its gasoline counterparts. MPG is outstanding (got 30 MPG NY to VA Beach with 4 adults and 600 lb luggage). Torque rivals that of V8 Model. Main disadvantage is that you can't use biodiesel with a bio content >5%. Compared to the 3.0 or the 4.8 L version, the diesel is a bargain. Yeah, it's a little louder than the 3.0, but 35d's sound under full throttle rivals that of the V8 version. Another downside is that you can't (or couldn't) get the sport package. Whether it's the X5D or the Audi Q7D, luxury SUV buyers should really consider the advantages in fuel economy w/o loss of performance.
We love this car. The diesel is a strong performer and good mileage. We have not experienced the lag time on start up that testers have stated. We got the 3rd row seat to accommodate grand kids and it works great for that, not enough room for adults though. The ride is quiet and firm which we like. We don't even notice the diesel noise, it purrs like a kitten!
We bought a BMW diesel X5 and there is a lot of good things too say like room, looks, fuel economy and performance however in the age of information all I can say is SHAME on BMW. With all the so called advances surrounding information systems BMW has missed the mark by more than a country mile. The important variables like oil pressure, coolant temperature and battery voltage level are all missing. This information is all "vital" since they provide valuable insight when a system is "starting" to fail. I prefer and I am sure that many other drivers would prefer to have maintenance done before you are in a location or at a time where help is hours away. Again SHAME on BMW & our salesmen.
