Don't pay a lot of money for it. According to this (
https://slickdeals.net/f/10389444-di...e-other-models) the bike sold for as little as $180 at Dick\s Sporting Goods in July 2017 obviously on closeout since it wasn't made that year. MSRP for the bike from 2013-2016 was from $360 to $450. Lots of people here look at the Bicycle Blue Book prices with more than a grain of salt.
It is classified as a hybrid bike, not a road bike. It is an entry level bike. The Amazon site says it weighs 33 pounds. Not lightweight but not the heavy crap sold by some mass merchandisers. If they hadn't designed it with the useless suspensions it probably would have been lighter. Apparently it came in two frame sizes (15" and 17") so you might ask the seller how long their inseam is compared to your own before wasting time going to see it.
You can read the reviews at Amazon as they are still there to be viewed
https://www.amazon.com/Diamondback-B...pe=all_reviews. It's obvious that a lot of the reviewers aren't avid cyclists who ride many miles. From reading the negative ones I guess you have to hope whomever assembled the bike knew what they were doing.
