It’s used, but I bought a Benz.
There are a lot of secondhand stores in this area.
I don’t want to get married to someone who is like a piece of used furniture.
The combination of kanji doesn't make perfect sense, but it's alright. Take something that's middle old and you have something that's used or secondhand. It's not 100% old yet... it's still in the middle, meaning you can give it to someone else to use, like your younger siblings.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
