I am pretty sure these are at Louie's BMW on Rt. 1. Pretty rough shape. The solid red one was probably in the best shape. I looked for parts on the white one last year and recall that it seems to have a crack free dash (although it had seen plenty of weather from a busted drivers window). If you look closely at the map you can see the blue w/ red top, white one and solid red one parked next to the boat. He owns a nice custom Tii that is worth checking out.
