I have nitrogen in my tires, 100% nitrogen that is. The air we breath is 78% nitrogen anyway, so when you top up the pressure with air at the local gas station you are only adding a few percent oxygen.
Frankly I suspect the benefits are quite minimal, dry air, free of water, is probably nearly as good, lets face it the outsides of the tires are surrounded by air every day, plus all the other pollutants you can think of.
If the price is right do it, if not tell your dealer you will try a test drive with it and if its that good you will notice and then come back to pay him in a few weeks.
Edit: Of course the weather temp and the tire temp affect the pressure in the tire, air and nitrogen are gases and obey the laws of physics (Boyles Law). There is nothing magical about nitrogen, no matter what the dealer says.
