Posible A8/8L purhase
 

Wife is in love with Audi A8's it appears!
2007 and later, although budget will dictate how much later. Want the 07 onwards for the timing chain and not belt. She also doesn't like the look of the earlier ones.....
Anything to look out for in particular? Engine reliability? Transmission? So on and so forth.
She is currently running an 03 Range Rover, and we have 3 Rovers all together, so complicated stuff isn't too much of a concern. I have all diagnostic stuff for them, so would look for the same for the Audi's. Any recommendations on that score? There are various ones for Rovers (TekPro, Faultmate, etc) and I have them all.
Thanks for any advise.
