Since this is the first “nice” bike I’ve ever owned, I opted to take it to a bike shop to fix some things I didn’t feel comfortable with myself yet. The gentleman working there told me it looked like a 1986 Trek 600 series and I was wondering if that was accurate. I’ve tried to do some of my own research but can’t figure out the difference between the Trek 600 and a Trek 660 etc. In the week I’ve owned it I’ve put on a couple hundred miles and am pretty excited. I have a ton of questions and nobody to ask so I figured I’d stop here and get the make and year for sure, and then maybe get pointed in the right direction for other questions. My intentions are to have a bike for touring. Thanks!

I’m guessing that it’s ’85 600 based on the Shimano 600 groupset, blue paint and more importantly the white San Marco Saddle that came with the 600 on that year. Sweet ride and enjoy it!
Here’s the vintage trek brochures website if you’d like to look more of it up yourself.

There is a serial number stamped into the bottom of the frame that will give you some information. Use http://www.vintage-trek.com/SerialNumbers.htm to assist in decoding!
Great starter bike! Ride as is, but good enough to upgrade.
Dittoing the ’85 600. A few years back one just like it was my first not-for-commute bike I owned, too–it’s a fun ride!
It’s almost certainly a 1985 660S, which had Reynolds 531cs tubing, which means the main frame tubing was double butted, but the seat and chain stays we’re not. This made the frame a bit heavier than the 660, which was double butted throughout, but anecdotally I’ve heard that shops back then steered riders north of 170 pounds or so to the 660S.
I have a 1985 660S (in teal). Awesome bike, but as others have said, it’s a road racing bike, not a touring bike. I’m guessing the eyelets on yours are for fenders, not racks, but curiously mine has no eyelets.
I love the bike because with 126mm rear dropout spacing you can squeeze a 130mm hub, which means you can run pretty much any modern drivetrain you want on it.
