By pure chance I came across a Porsche 550 Spyder as I was out today and decided to follow it. I'm glad I did as it pulled into the Oldtimertreffen just off Allmendstrasse in Zug.
They were also celebrating 125 years of Mercedes. There were Aston's, Jag's, a Capri, MG's, Mercs etc
They meet on the first Sunday of the month. I thoroughly enjoyed it and there is also a nice restaurant next door to the area.
