Should I buy a Miele C3 from an authorized dealer or a Miele Experience Center?

Hi all, Im looking to buy a Miele C3 to help with cat allergies and I have the option to buy it close to my home from a Miele Experience Center or a local authorized dealer.

The dealer offers a few things: free annual tune ups for life, 1 year free extended warranty, free service loaners, pro-rated replacement parts discounts after the manufacturer warranty expires, and discounts on bags, filters, and accessories.

I am not sure what benefits I receive from purchasing the cleaner directly from Miele Experience Center.

Please let me know where I should buy this vacuum from!
