I would have had the bike serviced, and maybe road it, but honestly I find vintage roadies uncomfortable. Road several over the last 20 years, and had one in the mid 80's that was bought new in a bike shop.
I was going to flip this (I rarely find anything worthwhile anymore) but decided to hold onto it. I could find 20 decent older road bikes for every 80, 90's steel mountain bike find....nothing really shows up cheap anymore.
Sorry, off topic.
