1993 G20 Hampton?
 

So I'm in the process of purchasing a 1993 G20 Hampton. I've been trying to find more info but it's nearly impossible. I noticed the Tiara model looks exactly the same aside from the interior being more upscaled. Can anyone confirm these findings or know more about the Hampton model? I also noticed that the seat has an emblem labeled, "OJMC" Any idea what that stands for?
