How Much does Enterprise preauth a major credit card for rentals?

I remember $50

I believe they add $100 to your total rental amount. So a $150 rental will be $250, a $350 rental will be $450.

Anywhere from a % of est total to as he gh as $200-$250 look in the terms before you book the rental

It depends on the number of days you're renting, but usually an additional $10

Thanks Elaine.
