Nice looking bike but I’m closer to $250 +/- $25. 501 frame. Needs new skins, tape and saddle at minimum. Maybe the French cachet commands more than this but I’m not thinking so on a mid-range bike.
The eBay part-out above is a tempting route. Good estimates except for the frame/fork which looks $100 too high to me (remember someone is eating $50 shipping on this). Unless you’re a hardened eBayer, fees, postage, haggling and profit-by-a-000-cuts can quickly dull the luster of this avenue.
