Are you just going to one dealer? There are tons in LA/OC so this shouldn't be a problem for you.
I haven't priced either car in a while so I don't know what their invoices are; I do believe the 5 is generally priced higher?
Keep in mind that if a piece of bubble gum is 25 cents and a bucket of [doo-doo] is a penny, you could certainly pay less for the bucket but look what you have.
