Camaro based Buick Riviera

I got inspired from the edited pictures then Kevin Morgan did with the Chevrolet Camaro by editing them into a Pontiac Firebird Trans-Am and a 1969 GTO Judge as well as my own sketches. [link] [link]

The more I looked to the current generation Camaro, the more I got some hints of the 1st-gen (1963-65) and 2-nd gen (1966-70) Buick Riviera. [link]

I checked some Buick Riviera pictures [link] and I decided to sketch imagining how a Camaro based Buick Riviera would look by using a front end more or less inspired from the 1966 model. Note then I'm not as good as Kevin Morgan.

Edit: I know then Buick showed a concept-car named Riviera at the 2007 Shanghai Auto Show [link] but I couldn't resist to imagine a modern interpretation of the 1st-gen and 2nd-gen Riviera.
