Art,
Your 67 is wonderfullllll. And I love the post 4 dr style/construction. I like also the more vertical windows. I had a 67 Pontiac that was very similar ... even the dashboard. I wonder how similar our engines are and also the transmissions.
This is Brown Bear. 73 Buick Centurion 4dr HT w 455 engine. She's all original except for mufflers and wheels. She's seen about 100K mi and I'm the 3rd owner. Had her for about 12 years. I tried to sell all my old cars (3) when we went to Ak but time ran out and I took Brown Bear w us. We drove her only on pavement (well 99% of the time) and she's not seemed to suffer from the Ak experience. She's a driver but probably only to the tune of about 5% of out road time. Brown Bear came from a era of wild styling including tail fins and much else but she is styled very tastefully I think. I approve of her style. She runs on regular fuel and gets way over 10 mpg .. probably 13 or 14.
