New to the forum

Is this the only x5 forum available? I was expecting something more...of..."only x5" forums...oh well...I drive a TL...as you can see below... but my parents are looking for a SUV and I recommended x5...so here I am searching for all the goodies and see where the possibly "used x5" is priced around... any suggestions on what liter to get....what options i would need definetly? thanks for the inputs in advance....
