Congrats!! I flipped a Centurion Sport DLX last summer...I bought it for 10 bucks at a garage sale...cleaned it up changed the dry rotted tires for a used set of Bontragers. I used it for an errand bike for several months before selling it for 200. It had a small ding in the top tube but ran great. It was an '87 with a Tange Infinity frame and a hi-ten fork. Lowly as Centurions go but I turned a good dollar on it. Good Job.
