I needed to book a specific car on a specific time to start vacation under a tight time schedule…read more Clerk did call me 4 h ahead offering me a to be upgraded car which means on top plus 250€, which I refused. As my wife needed to catch the car, only the upgrade car was available to be booked with additional insurance only. Having kids and all set and done to start under pressure, there was no chance to start discussing for alternatives. This was a 250€ plus "fun" on top.
Basically, if you need to rely 100% on what you booked, don't go Enterprise car rental.
