That is one beautiful Apollo.
Here is my 1980 Gran Sport bought at Calgary cycle for $385. It had the Shimano 600 grouppo some of which has been replaced. I had a chance to buy an Apollo with teardrop aero tubing and the Dura ace grouppo for the same price but it was a bright pink colour and my fragile sense of masculinity at the time wouldn't allow me to ride that particular shade. I sure wish I had bought that bike.
I bought a modern carbon fibre bike 2 years ago but still ride the Apollo in the rain and on the wind trainer. I am always impressed with how tight it still feels after 27 years. I intend on making it into a fixed gear one of these days.
