I am trying to make a plan for buying an x5 50i with features that wont be available until december. the problem is i plan on an extended leaving around December and getting back no sooner then April. Since i will likely need to try and time the order so i could take delivery in may. since i am waiting anyway should i hold off for an X5M.
When i drove an x5m last year i actually preferred the 50i but dont recall why.I ended up buying a q7 so my wife will keep the q7 and i will but the x5.
Thoughts??
Thanks
