Return to the BM fold

[Steve996]

Have had a number of BM's over the years, E30 318is, E36 M3, E39 535 sport but haven't had one for a few years......until today......just put down a deposit on a new (to us) family motor, X5 SD Msport black and beige. Took it for a test drive today, impressive machine!

Is there anything I should know about this model? Any essential tweaks/resources etc?
