I already own 2008 with steel suspension. I didn't know they've deleted power folding feature and auto tilting for 2009. My main reasons for 2009 are the upgraded RNS510 as you mentioned as well as being able to reprogram MFD to show the gear i'm in next to D or S and available blind spot monitoring system.VW only sent a few V8 for 2009 model year, all of them as corporate cars, and they are extremely rare. I used to own a 2008 V8 and it was great. Keep in mind the 2008 model years have power folding mirrors, 4 zone climate, auto tilting R mirror when in reverse, which can't be found on 2009. However, the 2009 has the RNS-510 which is a massive upgrade from 2008. (you can always install the 510 into a 2008).
