Need advice on buying a 99 Miata with an automatic
 

I'm going to go look at a 99 Miata tonight and was wondering if there is anything specific I should look for. I've bought and worked on enough cars to find bad wheel bearings, head gaskets, overall condition etc so that's not what I am asking. I have never owned a normal Miata and my question is are there any NB quirks the I should look for?

The car is a 99 non anniversary car with 100,000 miles on it. It has been stored winters and appears to have no rust on it. It has every option in the book I think including an automatic. It's black with tan leather and a tan top with glass back window. The seats, dash and top all look good but the head lights are cloudy so it may not have been garaged in the summers.

It looks completely unmolested except for a double duce roll bar and other than maybe some nicer summer wheels and going from a 4:30 to 3:90 diff for mileage I wouldn't do anything to it. Asking price is $5500.

So anything special to check for on this?

How did this turn out? I have a 2001 Auto that I love.
