That’s actually about what I’ve seen from most Toyota dealers in terms of price.
However, I’m with @keith - that emissions service is bogus. So is the fuel additive (a bottle of Techron would have been just as good). And what the heck is “additive throttle”? Is he saying he cleaned the throttle body? Well, I’ve seen some Toyotas (my Camry, for example), where doing this is actually a good idea to prevent a sticky throttle… but you only do it as needed, and even then, you have to be careful as some cars have coated throttle bodies that don’t like certain cleaners.
