Q5 Looking to buy a Q5


Drive safe, stay alive.
Hey all long term audi(s) owner here. Looking to buy a Q5 (2009-2013) and was hoping for a bit of advice

The only 2 criteria i have decided on is: S-line and Automatic

What options are basically must haves? Any highly recommended options, is the pan roof good?

Are there facelifts between 2009 upto 2013, any improvements between the years?

Would it be better to go for a 2010 3.0 TDI or a 2013 2.0 TDI? Anyone tried both?

Anything to look out for? common faults?
