I bought this Marin Argenta A6 for $120 CAD on Marketplace, and the seller turned out to be a mutual friend. The bike had some scratches but no cracks or dents, so I touched it up with nail polish. It has a Shimano Claris groupset, the brakes work well, and it shifts smoothly into every gear.
I only replaced the chain and gave it a tune-up, and it’s been riding great. But today, while cleaning it, I noticed a small scratch near the bottom bracket (see second pic). When I touched it, it felt like a semi-deep scratch, almost like someone might have used a tool to remove the bottom bracket.
Am I overthinking this, or should I be concerned? Either way, good deal or not?
