no ram air option on 95s unless it's a comp T/A which that one is not (they were all silver with a gray stripe) some people (like myself) have added ram air to our cars. my car has a factory WS6 hood and WS6 airbox. Also it still has the stock 95 T/A wheels. all the 96-97 WS6 t-top/hardtop cars had 17" wheels. IIRC only the 97 WS6 vert had 16s with ram air.
here is a pic of the airbox. this is what that one will look like if it has the correct airbox for ram air. it might have a suncoast ram air box or something though but this is the oem one.
the color looks either to be the dark purple or maroon. as for rarity i think they are both pretty rare colors with the maroon being a little more rare? they only made ~ 10,000 T/A's in 1995.
purple
maroon
