Dents are rarely cause for much concern in my experience other than for resale.
Quadra's are real nostalgic bikes for me I have their image imprinted on my brain. Good times.
Nice bikes, ace paint job too - hope the OP's Quadra is still in the original finish! Mine is British Racing Green all over at present and looking tatty. Off to the powder coaters for a nice shade of cream all over this summer and red lug lining added by yours truly to match the bar tape and bottle holders it'll be fitted with in its role as my commuter/tourer/winter bike.
