My G37 was convertible so no comparison. I'm just back from dealer and now have Cadenza SXL/Limted in my garage. I had looked at the Q50 Premium with Touring, Leather and Deluxe packages. The Q50 is replacement for G37 sedan.
I choose the Cadenza over Q50. In my opinion the reasons were:
- A bit nice ride, less road noise
- Roomier interior, especially the rear seats
- Better warranty
- 3 years service included
- A bit slower off the line
- No AWD option offered
- No all around the vehicle view (Q50 has ability to show 360 degree view)
They are both nice cars, but a comparable Q50 would have been about $10K more (actual purchase price as Kia had better rebate offers and more aggressive pricing). Price of Cadenza SXL/Limited I paid was $35,515.
Snow in the forecast so I guess I'll soon see how the Cadenza handles
