Vista Criterium Black

Hi,

Complete novice here so be nice :)

I'm a proud owner of an old black Vista Criterium bike. It has "Made In Japan" labels and marking everywhere, Suntour parts, Sanyo dynamo, and looks original and vintage. No major damage but has some minor rust. I'm curious how much it is worth. Since I'm new and can't post pictures or URL, I'd be happy to share them via DM.

Any info would be greatly appreciated. Thanks
