Are the packages too high?

I was reviewing the packages of the camry verses the prius.... the top of the line camry package does not quite have everything the prius does.. but the price difference doesn't seem to warrant the differences?

Are the prius's really marked up with the packages?..... or are we really getting what we pay for?

Example:
Prius package #8 or #F.... cost 6890.00
Package #8 -- includes driver and front passenger front seat-mounted side and front and rear side curtain airbags [2], anti-theft system and auto-dimming rearview mirror with HomeLink® [5] universal transceiver, Smart Key System, backup camera [3], Vehicle Stability Control (VSC) [4], High Intensity Discharge (HID) headlamps and integrated fog lamps, JBL® AM/FM 6-disc in-dash CD changer with nine speakers in seven locations, auxiliary audio jack, MP3/WMA playback capability and hands-free phone capability via Bluetooth® [6] wireless technology, voice-activated DVD navigation system [7], and leather-trimmed seats and steering wheel

Without going into further detail...I compared price from the prius packages:
Nav = 1900.00
Leather =1100.00
these two alone are 3000.00??? How do they do it on the camry and add other things also for the same price?...

If package #8 or #F is 6890 and has NAV and leather.... are ther 3890.00 worth of extras the camry doesn't have that also has NAV and leather? The Camry has heated seats that the prius doesn't have. They both include the CD but the camry does not have 6 disk changer included unless you pay extra.

The point it that its tough to account for 4000.00 difference when adding up the extras?

I know the HID's are expensive..... but not that much?

Can somebody help me here?
