Look for another used bike for about $20 and cannabilize the parts. Older Sun Tour deraileurs would be nice on that bike, as would a set of "true", hop-free alloy rims with complete quick release hubs. As for cleaning it up, try Fantastic (some Lysol, too, in that Peugeot's case ) or a similar cleaner and a good rising off with a garden hose. Then try a $1.99 container of Turtle Wax Polishing compound to bring up the shine in the paint, followed by a coat of car wax. To check the frame, look over the seat and chay stays...are they "bowed" inward on one or both sides? When the wheels are set in correctly is their equal distance to the stays and fork blades on either side of the rim? Does the head tube and front forks seek to flow in a straight line, or does the rear of the tire come too close to the down tube? Up by the head tube, are any of the other tubes crumpled in any way? Does it just look normal? For bar tape and other stuff check out Nashbar and Perfomance online. They have pretty good specials every now and then. And, wow, nothing beats "Curb Side Treasures"... the thrill of the hunt...the joy of discovery...and they are F-R-E-E!!!
