I'm looking for a bike for commuting 7 miles to work, exercising in hilly parks near Memphis, and light touring, maybe weekend trips.
I found an older used Trek 620 at a bike shop here in a Memphis bike shop. It's not in pristine shape, there are a number of scratches, it's been in a warehouse, lots of dirt, old tires. It has a tall frame, with the top bar about an inch clear below my crotch. Wheels are true. I took it out for 15 minute ride, don't see any real issues except these:
Handlebars are a little narrow for me, they are drop bars, they look original. Could I switch these out easily to wider bars?. Otherwise, the fit in general seems okay, full extension of my legs, the handlebars can raise up plenty high if needed.
There doesn't appear to be room enough for full fenders. For commuting and light touring, this is an issue. I looked around online, there are some narrow ones that could work.
The store wants $350 for it. I don't know the serial number, so not sure of year, or where to look on the bike. Not sure if this is a good deal. I'm not experienced enough to know if the components are good. The derailleur said Shimano 105, as did the brakes I think.

Otherwise, I'm probably going to spring for a new Surly cross check for $1150.

Any suggestions? Is it worth $350? I'm not interested in restoration, as much as a quality bike. The best part of this bike is I think I can fix most anything on it.
It has cantilever brakes, which worked fine. Color is light bronze metallic.
