09 Yaris Sedan/Sedan S option packages?

[PoorEcho]

Hello. I'm about to buy an 09 Yaris Sedan because my 03 Echo was wrecked (not my fault!) and I loved my Echo. I've been trying to compare prices using the Toyota site and the AAA page but I am confused on the options between the S and the non-S models.

Here is my wish list:
- Automatic
- 15" wheels
- Power locks, doors & windows
- keyless entry/trunk popper
- alarm system
- MP3 CD player
- rear defroster, etc.
- fold-down rear seats would be nice

From what I am seeing, it seems that the S comes with the 15" wheels and the MP3 player but the non-S doesn't.

There are two different alarm systems it seems:
ANTI-THEFT SYSTEM W/ENGINE IMMOBILIZER (PN) or
V.I.P. RS3200 SECURITY (V5)
Both seem to require the power package, which I plan to get anyway. But what's the difference?

So either way it looks like I'll need the all-weather guard, the power package, and one of the alarm systems. But if I go non-S I would also need the convienience package. Is this right?

Oh, and one more thing. I had a Certified Used car with a 7 year warranty before (it was included in the price). Is there not a warrany included with a new car?

Thanks for any input! This is going to be my first brand new car and I don't know anyone that is good at figuring this stuff out.
