Yamaha Retro Spares in Australia sells vintage bikes and they would have little trouble moving that bike for 7,000-8,000 so it may be a bit high. Depending on exchange rate that may be around 4,200-5,000 U.S. Not to out of line when that could bring 3,500-4,000 in the States. The 70, 71, and 72 are the most desirable for collectors. That one is a beauty.
