1. Overture Audio in Ann Arbor has a used VT-200 Audio Research for sale in their basement right now.
2. The Porsche Club of America magazine Panorama has a Beverly Hills MI advertisement for a 1987 911 TURBO (w/tail) convertible. I think there were only 150 Turbo Targa and Turbo Convertibles made for the years 1987-89, this is a very rare car, Cobalt Blue exterior.
PM me and I can get phone numbers to you, I'm broke myself, and should say I have no interest in these items other than if you get one I will be green with envy.
