Car hire with Centauro

I always used Centauro to hire cars direct or Firefly with Doyouspain.com

Does anyone know the best broker to hire a car with Centauro preferably in Euros.

The Centauro website now only offers cars with full insurance, which now is too expensive.

I have my own insurance and don’t mind them blocking my credit card.

I do hire cars quite regularly and the two companies are my preferred choice.

PS it’s nice to see car hire prices are falling again

Thanks in advance
