This is the most underrated gems in the used diesel SUV market—but only if you’re the right kind of owner. Powered by the soon becoming legendary M57 inline-six diesel engine, this version of the E70 X5 combines German engineering with long-haul durability if treated right….and by treated right, I mean ideally maintained by someone who can turn a wrench and not the type of owner who wants to drop it off at the dealership for every noise or light. This vehicle is ideal for the hands-on car enthusiast who appreciates the mechanical integrity of a proper diesel engine and doesn’t mind putting in garage time to keep it in good shape. If you're someone who already loves BMWs and understands their quirks, this vehicle will feel like a rewarding project and a fantastic daily driver in one package. The M57 diesel engine is incredibly robust and becomes one of the best engines only with one huge caveat…the emissions equipment needs to be removed. In fact, I would not recommend owning this vehicle if you don’t plan or cannot do this in your state legally. Once deleted, this engine opens up and delivers a strong blend of torque, horse power and efficiency, making it an excellent tow vehicle. It's perfect for hauling a car trailer, camper, or family gear around without struggle. Stock, it’s already torquey, but with the deletes and a mild tune, this becomes a real beast without sacrificing reliability...and if given a race tune, this thing will hurt other drivers' feelings pulling from stop lights or on the freeway. The chassis overall is “decent” (Being said by a vintage BMW enthusiast, this is very much a compliment to today’s standards), but there are known maintenance pain points that a mechanically inclined owner should be aware of. If you plan to purchase from a used dealership or private seller, you’ll most likely need to do a suspension refresh including replacement of struts, bushings, arms etc.…possibly an engine refresh including valve cover seals, intake manifold cleaning and replacement of other various leaky seals…work on the cooling system including but not limited to replacing lines, hoses, main/expansion coolant tank as these are plastic and will crack and fail due to heat over time. There will be some normal interior wear including the finishes of center console buttons peeling off but are easily replaceable. Something important to note when purchasing is the interior sunroof shade condition, including whether it is completely operable and if there are any signs of sagging/peeling fabric. Any issue with the sunroof should reflect in the price as this item is very intricate, expensive, and difficult to work on. These aren’t dealbreakers though...just things to note when looking to purchase and if they’ve been covered in recent maintenance...if they haven't, plan for work that will inevitably need to be done. Again, don’t expect it to be hands-off, you’ve got to earn this one…But if you're up for the task, you’ll be rewarded with one of BMW’s most versatile platforms.

I brought my x5 back in 2015 (3.5i) I am telling you stay away from it and don't think of buying this car you would be lucky to sell it for 7.5k usd it is the least reliable. car when i got it new from bmw 2 weeks after I got it it immediately broke down on the highway (transmission failure) and you will never not hear the ding (meaning somethings wrong) it's either tmp, check engine or overheating.

As a proud BMW owner since mid-eighties, to include owning a 2001 E-53 X5 while stationed overseas; the 2011 X5 50i is one of the best-looking and best performing BMW SUV we've owned (especially with sport activity package, adaptive drive, and dynamic stability control). In 2011, our newly purchased X5 E70 with MSRP of over $80K, was loaded with all BMW options offered, expect active cruise control. When we recently purchased a BMW X7, the BMW dealer trade offer was low, so we decided to keep our X5 with only 48.8K miles, my wife loves it. The only major repairs we have done so far are to replace the oil pan gasket (due to a small leak), and a couple of new batteries. The X5 still runs like new, and we plan to keep it as long as possible.
