Looking for a car mechanic for side mirror repair

Good Morning everyone!

Does someone know a car garage worth recommending? While my car was parked in front of my house, a bus side swiped it and damaged my side mirror. Luckily it looks like only the plastic casing is damaged - it folds and opens as before and the mirror glass is intact.

I went to Renault and they estimated the damage for 900 euros, which is... surprising. I looked up spare parts for my car online, and even if the whole mirror needed replacing, it wouldn't amount to 500 (the insurance estimate for parts).

It is my first car, so I would like to find a good mechanic anyway, just to have some contacts for the future. This time I don't care much about the price, as the STIB insurance covers it, but I don't think I will be back in Renault for other repairs.

Apart from the side mirror, I also want to change my tyres from summer to all-season, so if someone knows anyone efficient, that will be well appreciated.

Thanks!
