From the hubcaps thats the original 4WS model, great car and I had several of these back in the day.
Always had a soft spot for the Prelude, especially the previous model 20i-16, and keep dropping into conversation that I might get one as a town runabout, but I'm not allowed too 
Keep it stock, give it regular servicing and when you sell up to the NSX please let me know ...
