The greenhouse for the S90 and Cadenza are nearly identical, esp. the rear window panel (diff. for the G80).Do a comparison of the S90 with the G80 and you will find more similarities than with the Cadenza's quirky styling.
I am just glad that we on this thread and on others I guess, still have the car bug and contribute to the variety of brands and car types out there. It would be a dull life if we drove around in silver Chevy Cruzes all around.
Typo on my part.By the way, the 3.8 is a V6, not V8. Had it on my G80 and loved it. My G90 has the 3.3TT and it does scoot with more fervor. 3 months into this lease and already thinking about the next car - decisions decisions.
