Dealer Added Accessories? '08s?

[mutatio]

1st post! woot!

Hello all!

I'm writing to check in on which accessories I can get added or subtracted at the dealership. I know the power/convenience packages and whatnot are from the manufacturer. In particular I've noticed that many of the cars come w/ the carpet mats and foglamps, both of which I could do without to help keep costs down. In specific, I'm curious about the keyless entry and the anti-theft engine immobilizer. Does anyone know if these are added at the dealership? It makes sense, since the hardware would already be installed from the factory for the upgrades to be taken advantage of.

Also, when did the Yaris first come out in the US? I noticed early posts here from January 2006. I'll be looking to purchase in January-February of 2007, as the lease on my Saturn is up the 2nd week of Feb. I'm just wondering whether the 08's might be showing up at that time. If so I'd be curious to see if they've melded some of the accessories into the packages. i.e.-power package w/o keyless entry? <scratching head quizically>

Thanks!
