2001 BMW X5 SUV 3.0i AWD 4dr SUV (3.0L 6cyl 5M)
Stay away, stay far away...
 We bought this as an alternative to our minivan, thinking we would get the same quality from the X5 as our other BMWs. From the start we had problems. Within the first 3 months we replaced the oxygen sensor, max air flow regulator, thermostat, and lower control arms, along with what seemed like a half dozen sensors that keep going bad. Even the general maintenance costs are very high, as its costs $120 for an oil change (8 quarts premium synthetic) and 91 octane gas, performance brakes & tires, etc. We ended up selling this and taking a loss. Back in college I had a 1984 318i and later a 1995 325i convertible that were both extremely reliable. What happened BMW?
