Hi,
I can relate to your situation since I had a nice bicycle stolen over a month ago even if it had the Garage 529 registration with the Montreal police. To replace it I bought an old 1980’s mtb, replaced the tires and brakes for my daily commute since the rest of the components were fine. The last thing I added is a milk crate on the rear rack.
If you want to make it look used. Just take a steel tool and chip away the paint. After, taken some ugly paint such as rust oxide primer and randomly apply with a brush.

You can’t stop all the bike thieves but it helps.
This is mine. It looks worst in person.
