Is this bike worth it for $300

Hi everyone,

I have the opportunity to buy a Stevens Gran Turismo for $300 and I’m wondering if it’s a good deal.

How I plan to use it:
• Daily commute (about 10-15 km) in the city
• Longer rides (50-100 km) with some luggage
• Bikepacking trips
• Should handle light gravel and forest paths

Bike condition:
• Weight: approx. 11 kg
• Some paint damage
• Front mudguard torn
• Brakes on the shifters not usable (design-related)
• Otherwise technically flawless and well maintained

According to the specs, it has a Shimano 105 3×10 drivetrain, a lightweight aluminum frame (10.8 kg), and a drop handlebar for multiple hand positions. It seems to be a light touring/randonneur bike.

I‘m also willing to invest some money into upgrades or repairs if necessary.

Is the Stevens Gran Turismo a good choice at this price, or would I be better off with something else in this budget?

Looking forward to your advice!
