* Based on opinions and should be considered as general guidance only.

• Reliability (4)
  4 out of 5 stars
  The 3800 Series II engine is legendary for its longevity and can easily surpass 200,000 miles. Common weak points are non-mechanical, such as failing window regulators and interior trim pieces that tend to loosen over time.
• Maintenance (5)
  5 out of 5 stars
  Parts are incredibly cheap and plentiful due to the shared GM G-platform. The engine bay is relatively spacious, making it one of the easier modern sedans for DIY repairs and routine fluid changes.
• Technology (3)
  3 out of 5 stars
  For 2004, the available Head-Up Display (HUD) and Monsoon premium audio system were standout features. However, the rest of the cabin is a sea of dated GM plastic buttons and basic digital readouts that felt behind European and Japanese rivals.
• Comfort (4)
  4 out of 5 stars
  This is where the Bonneville shines; the 'cockpit' style interior offers incredibly plush seating and massive amounts of legroom. The ride quality is soft and effectively soaks up road imperfections, making it an ideal highway cruiser.
• Dynamics (3)
  3 out of 5 stars
  The 3.8L V6 is a workhorse, providing smooth but uninspiring acceleration. While the SLE trim features a slightly firmer suspension than the base model, it still suffers from significant body roll and a numb steering feel common to large front-wheel-drive sedans of the era.
