Welcome to the ownership club! You only have 2 posts but hopefully you've on the site for a while and using the resources. If not, make sure you familiarize yourself with the NSX Wiki on this site. It can be found on the red action bar at the top of most pages and contains a wealth of information about the car; maintenance topics; popular modifications; etc. Of course you can use the Forums search function but sometimes going to the Wiki can be easier than wading through pages and pages of Forum posts. Unfortunately, the Wiki content has been locked down for a while and some parts are old .. but then the car didn't really change all that much over the years so much of the information is still appropriate.
Hopefully the previous owner(s) kept a maintenance history that you can refer to. The first thing you should get a handle on is when the timing belt/major service was last done. Acura recommendation is 7 years or 90k miles whichever comes FIRST. So, based on the age, it should already have been replaced several times. If the belt fails, bad & expensive things can happen. Hopefully it's been changed recently .. if not, start putting some money away and have it done soon. And if the clutch hasn't been done, you're probably nearing its limit as well. It appears someone has made some audio changes so at least you shouldn't have the typical OEM Bose audio issues.
Now, just get out and enjoy it!
Enjoy .. Ian
