Quick question about buying TRD parts
 

To those of you who bought TRD parts and got it installed from your dealer after you had already bought the car...is it something you pay for separate? or gets added on to your monthly payments\ pay off balanace?

Paid separately. Most of the stuff TRD Japan or USA could be installed by yourself as long as you have a place to work on it. I think the typical cost for installing an exhaust or coilovers is $100. With that you could buy all the needed parts to install it yourself.
