Buying a new Honda, extended warranty or no?

[NL__Fool]

So I purchases a 2007 Honda Civic LX and I am picking it up on Thursday. I have until then to decide if I want to buy the extended warranty and/or the rustproofing/scotchguarding package.

I have never leased or purchesed a Honda before.

I have always leased and never bought a car before, so these options were never a concern for me.

With hondas reputation do I really need an extended warranty plan?

I plan on keeping this car for probably about 7-10 years and I will probably only put about 10-15K a year on the car
( or 6k-9K miles)

I can purcases the extended warranty when my original warranty is up but then it costs more so Do I really need it?

What about the rustproofing and scotchguarding? Do cars normally start to rust with age? How long does it take before rust start in on unprotected cars?
