Advice needed: Should I buy this Specialized chisel bike from marketplace?

Hi everyone,

I’m a beginner to mountain biking and am planning to hit up some trails soon. I found a Specialized Chisel bike on Marketplace that I'm considering buying, but I'd like some advice before making the decision. The bike looks great in the pictures, but I’d appreciate any insights from those with more experience.

Here are a few details:
– *Condition: Used for a year
– *Price: $199 CAD

I’ve attached pictures of the bike for reference.

Questions:
1. Is this a good deal for a Specialized Chisel, especially for a beginner?
2. Are there specific things I should check for when buying a used bike?
3. Any other advice or things I should consider for someone just starting out?

Thanks in advance for your help!
