Even though i drive my 1964 riviera every day, the furthest i had ever driven was a round trip of 250 milles. Yesterday i traveled to the Good-Guys show in Lincoln, NE which was a 500 mile roundtrip. Needless to say, the old gal performed flawlessly. I only saw 1 riviera (1963) at the show and was reminded of how unique these cars are. Will try and post some pics of the car that was at the show as it was a custom with a small block chevy and 20" wheels. All of the work was done by the owner who drives it to every car show regardless of distance! I had approximately 50 people comment om my car during the journey and most were suprised it was my daily driver. I reminded each one that when Buick produced these cars they were MEANT to be driven everyday! So get out there and drive your Buick!
