Armrest answer
I bought a new 2018 iA. I wanted the armrest so I added it into the deal. Ready? Ready? $395. The armrest is $195 + tax, say $215 then labor is READY? $149 an hour. So yes I bit the bullet and bought one. I would of installed it my self, but if it goes wrong it will be on the dealer. Besides, l plan on keeping the car for 10 years or more. NOTE- mud guards $105 + tax = $115 plus $149 labor. These I bought off ebay and can install these myself and finally caught a break. Also, I bought everything from Weathertech except the front seat protectors and got a $25 set off Amazon. Good Luck with yours.
