What is the difference between the standard and deluxe interiors?

I'm thinking that my car has a standard interior because none of my options on the order sheet say anything about "deluxe interior". I do have things like BELTS_DELUXE, STRG WHL_DLX, CLOCK_ELEC but that's about it for the interior.

And on another note...the AC was pretty **** expensive. The total car was $2906.52 (before shipping) and the AC alone was $271.32. That's almost 10% of the ENTIRE car extra for AC. Yikes, no wonder too many people didn't get it.
