Replaced an old Weber Silver, over 23 years old, still working just getting a little rusty. 
This Genesis E-315 with its front to rear burners and SS heat deflector plates and SS flavorer bars make for a very nice cooking grill. Enjoying the grilling experience on this grill. Very well built. 
From my experience with multi Weber grills over past years, never had a problem getting parts. Will continue to be a Weber customer.
