Upgrades:
When new: Mazda rear cargo shade, works excellent
When new: Mazda remote start, terrible design, waste of $400

Added 3M clear door edge tape to hood, 4 doors, and rear lift: $25 for 2 rolls Amazon
Wear:
Door arm rests showed wear within 2,000 miles, understand they changed them for 2014. A damp wipe helps.
Back lift where bike rack rubs and where garage door closed while lift was up. oops. $12 eBay touch-up paint.
Some pitting on front plastic bumper from stones, touch-up paint.
Not a single rattle, very very little wind noise
Other than stone dings paint looks like new, self-wash monthly and self-wax twice a year.
