maybe in my area Honda always comes out with the better deal with their 100 month warranty.
OP if you go to Honda and show that corrosion you will prob get a prorated deal on battery or if best a new one. Let us know how you make out.
My car was totaled and took out the manuals with literature. Also have the original window sticker for 2017 EX hatch.
I assume these cars are becoming more secondhand now some of these items might be missing. PM if interested.
Bought from college hill when they had a sale. Shipping is standard. If the item is oversized or heavy there is no wiggle room. You save on sales tax if your out of state.
