"Should I bother to look...."
If you feel strongly the house is overpriced "for the market", then by all means take a look at it.
If it is indeed overpriced, than fewer people are looking at it than normally would.
"Buyers" in this internet age are savvy. If a home indeeds appear overpriced, than fewer people are making appointments to see the home. What that can mean is that the Seller, when seeing few people making appointments to tour their home, may indeed entertain a low offer that perhaps you are (or will be) prepared to make.
If it is overpriced "for your pocketbook", but priced well for the market, then you may well be wasting your time in considering both looking at the property and following up with offering something very low.
"My guess is.... $275,000 - $285,000"
Comps within only the past 6 months show sale prices with a high of $329,000 for 3 bedrooms/2baths/SF of +/- 100 SF on either side of the SF of 82 Lenox.
Factors you may want to add in or reconsider for your valuation of only up to $285,000 is the relative newness of construction and the school district of Buttonball being one in very high demand at these price ranges in Glastonbury.
Can you get it for $275,000 to $285,000?
Ya just don't know the motivation of a Seller. So, perhaps.

82 Lenox is being sold with the condition "contingent upon owner finding home of choice" meaning quite frequently that the Sellers probably don't have to move, so an offer out of range is probably not going to be considered.
