The two biggies that they try to muscle on to you will be:
>Extended Warranty / Service Plan
>Paint and Upholstery Protection Package
My opinion...turn them down even if they try to scare you to death with their tactics.
Other extras may be worthwhile...
Slide awnings is one that I like...but vigorously negotiate price for all of them.
