if you aren't familiar with these things, the only two i'd get from a dealership are undercoat and rust protection. essentially everything they offer, you can purchase and do yourself. it's just a matter of whether or not you're comfortable doing it (or learning how to) by yourself.

i actually have the same paint sealant that Honda uses on their new vehicles :smug: :D

as for the alarm system, it's not really something i'd buy for a brand new car. 2007+ cars all have a standard immobilizer installed and you've already got power door locks too. if you really want piece of mind, I'd recommend you have a Compustar 2-way alarm installed by a local shop (like Sounds Good :)). when i worked at Honda, they charged a customer (also with a new cr-v) something stupid like $1100 for the alarm and it was a knock off of Compustar. the 2-way remote looked HORRIBLE.
