            Sts Introduction:
        
        
            The STS (Seville Touring Sedan) replaced the outgoing Seville. It was based on GM's 'Sigma' rear-wheel-drive platform, shared with the Cadillac CTS and SRX. The STS aimed to compete directly with established European luxury sedans.
        
     
    
        
            2007 Model Year Updates:
        
        
            For 2007, the STS received minor refinements. The primary focus of the manual would be on the features and systems introduced in the previous model years (2005-2006), with any updates for 2007 incorporated.
        
     
    
    
        
            Assembly Location:
        
        
            Lansing Grand River Assembly, Lansing, Michigan, USA.
        
     
 
    
    
    
        
            Segment Performance:
        
        
            The 2007 STS was generally well-received for its comfortable ride, potent V8 engine option, and luxurious interior appointments, although often ranked slightly behind its German competitors in outright driving dynamics and brand prestige.
