This is my daily driver, a 1992 Trek 820 in electric blue with black spatter. I got it for free from my brother about a year ago, and have since put ~4K miles on it. I have another 820, and I love these bikes. They make great city bikes. They're dirt cheap, geared well for the hills in my area, and they just work. It's nice to have something in your life that you don't ever have to even think about. I've made some upgrades for my use, including the racks, basket (I have a second I attach to the front rack for Costco runs), fenders, street tires, and high rise handlebars.
You can identify the year by looking at the model and color here:https://vintagetrekarchive.com/model_numbers1.htm
My other 820 is from 1995, and it is a very pretty ice cyan blue. It's supposed to be a fade to black int he rear, but it appears that they must have ran out of black that day, as there is only a slight hint of darkening in the rear of the bike.
Alright, it was an 96 830 mtn track in dry silver! With the red front suspension. Somehow I never took any pictures of it unfortunately despite riding it from age ten to twenty something, never realized that until filing the police report ๐ญ
