Looking at buying a 2009 X5

[Thrawn]

So my 740il had a timing chain failure, and my other car is in the shop from being rear ended. I drove a 2011 x3 yesterday, and have an appointment to drive a 2009 x5 with the v8 today. I will probably buy one of them. Don’t know much about the x series. Anything to look for or check? The x3 is at my local bmw dealership, the x5 is at an independent dealer. Both are with in $100 of each other in price. The x3 has 113k Mike’s the x5 has 105k miles. Thanks for the help.
