As to the second question...

I don't think there have been any major issues with the 05's

If you are looking at an 04, note the VIN, if it is very low (< 5000 or so) you might watchout for the tranny on the Manual.

Everything else is manageable. There are other issues, all fairly minor and/or easily fixed by a dealer.

(The 5000 was a guess-timate. Anyone know where the 1st gear fallout really ends?)
