            Honda D-Series (e.g., D14, D16) and Rover K-Series (e.g., K16) engines were prominent.
        
     
    
        
            Displacement Range:
        
        
            Common displacements included 1.4L, 1.6L, and potentially 1.8L or 2.0L diesel variants.
        
     
    
    
        
            Horsepower Range:
        
        
            Typically ranging from approximately 75 hp for 1.4L engines to over 100 hp for 1.6L engines, with performance variants like the 420 GSi potentially offering more.
        
     
    
        
            Torque Range:
        
        
            Corresponding torque figures would vary significantly based on engine size and type.
        
     
    
    
        
            Fuel Delivery:
        
        
            Electronic Fuel Injection (EFI) for most petrol engines. Some earlier models or specific variants might have used carburetors, but EFI became standard.
        
     
    
        
            Engine Management:
        
        
            Engine Control Unit (ECU) controlled fuel injection, ignition timing, and other engine parameters.
        
     
 
    
    
    
        
            Oil Change Interval:
        
        
            Typically every 6,000-10,000 miles or 12 months, depending on driving conditions and oil type used. Specific interval for Rover K-series engines might be tighter. Check manual for precise recommendations.
        
     
    
        
            Timing Belt Replacement:
        
        
            For Rover K-series engines, timing belt replacement is critical, usually around 60,000 miles or 5 years. Failure can cause catastrophic engine damage. Honda D-series engines might use timing chains or belts with different intervals.
        
     
    
    
        
            Engine Oil Specification:

            Brake Fluid Specification:
        
        
            DOT 3 or DOT 4 glycol-based brake fluid.
        
     
    
        
            Transmission Fluid Manual:
        
        
            API GL-4 or GL-5 gear oil. Viscosity typically 75W-80 or 75W-90.
        
     
    
        
            Transmission Fluid Automatic:
        
        
            Typically Dexron II or equivalent for the automatic transmission.
        
     
    
    
        
            Cooling System K Series:
        
        
            Head gasket failures are a known potential issue with Rover K-series engines, often exacerbated by coolant loss or incorrect bleeding procedures. The 'dog leg' hose and coolant leak issues are particularly noted.
        
     
    
        
            Electrical Issues:
        
        
            Corrosion on electrical connectors, particularly in older models, can lead to intermittent faults in lighting, ignition, and engine management systems.
        
     
    
        
            Suspension Wear:
        
        
            Bushings, ball joints, and anti-roll bar links can wear over time, leading to knocking noises and degraded handling.
        
     
    
        
            Rust:
        
        
            Like many vehicles of this era, rust can be an issue in common areas such as wheel arches, sills, and around window seals.
        
     
 
    
    
    
        
            Rover Heritage:

            Second Generation:
        
        
            The second generation (HH) arrived around 1995, introducing revised styling, updated interiors, and further refined powertrains. It continued the Honda partnership with shared platforms and engines.
        
     
    
    
        
            Production Locations:
        
        
            Primarily manufactured in the United Kingdom.
        
     
    
        
            Production End Year:
