Things to look
for
  - Aero wheel package
    (standard equipment on 91 & 92  5-door turbos) 
    
    
      - 
 Three spoke 16" Aero wheels 
 
      - 
 Lower, stiffer suspension 
 
      - 
 As close to an Aero as you can get without having an Aero. 
 
    
     
 
  - 9000 S and most other
    models are otherwise generally "loaded"
    
    
    
 
 
  - Turbo models are much more
    powerful than non-turbos
    
    
      - Potential for having been
        abused is obviously somewhat greater
