Down here in San Diego they ask for 8 at the shops.
Last lime i saw an Add on craiglist the guy was selling a vintage playmobil buildings and a lot of tracks, he wanted 800 for all the of tracks, the lowered to 600. but doing the number it was around 4.5 the piece. But the condition of the track was pretty used, so my final offer was around 350, (around 3) took him a few weeks to took my offer, but the day i was suppose to go pick it up he told me someone pay the price he was asking for 600 at that time.
So, 5 is good price for a new track
And 3 used one!
