Pros & cons

Pros

  • Rear-wheel-drive chassis with well-weighted steering makes it one of the more fun-to-drive sport sedans and coupes of its era.
  • Strong 3.7L VQ37 V6 (around 328 to 330 hp) delivers genuinely quick, engaging acceleration.
  • Low repair costs and strong reliability for a used luxury car, RepairPal rates it 4.0/5.0, well above the luxury-midsize average.
  • Affordable used-luxury value compared with a similar-age BMW 3 Series or Audi A4.

Cons

  • Firm ride and noticeable road noise make it less comfortable than softer luxury rivals.
  • Thirsty for the class at roughly 20 mpg combined, and the V6 requires premium fuel.
  • Dated infotainment, a small trunk and a tight rear seat (especially the coupe) limit everyday practicality.
  • Most cars carry the Takata passenger-airbag recall, and early years added dashboard and steering-lock issues, verify the repairs were done.
