Welcome to the forum! The first thing I recommend you do is go to a dealer and order an owner's manual. This car has a lot of features and there' no way you will discover them all on your own. If you do your own maintenance, the service manual is available as a .pdf. Use the "search" link at the top of this page and type in "service manual" and you will find it.

As far as other mods go, just about everything has been tried and discussed in the past, so again, use the search function and poke around a bit. There's a whole lot of really good info here.

A really good project to start you off is Pelked's "Biggest stereo bang for the buck mod", which will cost you about $2.00 and will make your stock stereo sound about 1,000% better. A link to that thread is here.


Have fun!
