Is this used Trek X-Caliber 7 worth it for a complete beginner?

Hi everyone,

I found a used mountain bike near me and I’m completely new to MTB, so I’m trying to figure out if this is a good deal and whether it’s worth getting as a beginner.

It’s supposedly a Trek X-Caliber 7 (hardtail). The seller says it’s in good condition, but I don’t have much experience judging bike components or wear.

Since I’m just starting out and want to see if mountain biking is something for me, I don’t want to overspend — but I also don’t want to buy something that’s overpriced or problematic.

What would something like a Trek X-Caliber 7 typically be worth on the second-hand market? Are there specific things I should check or ask about before buying?

Any advice for a total beginner is very welcome. Thanks!
