1966 Buick Riviera GS, SOLID, Colorado Rust Free car! Great Project!!

1966 Buick Riviera Additional Info:

Hello everyone. I am looking to sell my late fathers 1966 riviera. My father was a true lover of all things Riviera, and he even met my mother in a 1963 Riviera that he still owned when he passed. However, when he passed away in late 2016, he left me with 6 Riviera's total. I wish I knew the history of this car, but I don't.
I know that he owned it for years, bought it from another Colorado owner, drove it occasionally with his dealer plate, but that about all I know. I have no clue if it is a true GS or not, but it does have the emblems, and the GS dash trim. I really don't know much about this car other than it was a running/driving car in 2016 when he passed. It was driven from his restoration shop and parked in the outdoor storage shortly before he passed, and it has not been touched since.
The right rear tire will not hold air, and the headlights are stuck in the open position. The front bumper looks like it has a slight impact, and the gas has gone bad in the tank (smells bad). This is a project, but with minimal effort you could have a running driving project to work on as you enjoy it at the same time. I have a clear Colorado Title for the car, in the previous owners name (my dad was notorious for not putting cars in his name, but rather leaving the title "open"). The interior is all there hoever the seats will need to be re-covered, and the rest of the interior is what you would expect from a project. It's not terrible, but will need attention here and there.
The engine does not appear to be original to the car. The engine stamp is KT, which from my research is a 1964 401 cubic inch engine. The intake is dates 3-2-66 and is red, but the rest of the engine is the early Buick teal green color like 1963-1964. With that said, this is a SOLID car, with some very slight bubbling around the left rear quarter opening, but from climbing around/under the car, the floors and trunk are solid. Also, the body lines and body gaps are beautiful and it looks like some body work has been done already. This car has been in rust-free Colorado for decades and it shows!. I am sure I forgot a lot, so message me with questions or if you want a photo of a specific area.
