I've got an 82 610 that I picked up for my daughter. It's nice enough, and she's still too small that I'll be riding it once in awhile in the spring. It's got the Suntour BL derailleurs and they shift real well. In fact, they shift nice enough that I bought a set for my Gitane Tour de France to replace the Ofmega's that were on it (yes, I kept the Ofmega's).

The only thing I found when overhauling the bike was some mild surface rust in the bottom bracket and seat tube from water presumably getting in via the grooves on the seat post. It cleaned up easily and everything went back together great.

Enjoy the bike - it's a great one.
