Damaged car and tried to get us to upgrade our cover!

Excellent

Renting a car in Europe is actually quite convenient, as long as you have all the necessary documents, the process is very quick. However, the rental office may upsell insurance and vehicle upgrades. Personally, I think buying full insurance at the rental office is necessary when traveling abroad—it’s more convenient than dealing with claims back home after an accident abroad. So I purchased it. As for the vehicle upgrade, since the available upgraded model was the new Mercedes C200D, and as a car enthusiast, I couldn't resist choosing it. Overall, spending money always feels worth it.

The vehicle was poorly maintained; after driving less than 100 kilometers, an AdBlue warning appeared. Not having driven a diesel before, I didn't know what AdBlue was and almost had a breakdown. Ended up spending money on AdBlue myself, which delayed my trip by nearly an hour.
