Welcome and congratulations!

You didn't mention a pre-purchase inspection - did you get one? If not, one of the first things to do is to change the oil/filter and get the car inspected from top to bottom at either a dealer or a local independent repair shop. This will give you a starting point on the car in terms of maintenance and/or needed repairs.

If you're new to a convertible, its likely that you're going to hear a lot of noises that normal that you've not heard before. The soft top can sometimes muffle certain noises that are clearer/louder with the top down as well as amplify others that you can't even hear with the top down. In time you'll get used to what is normal and not normal.
