We recently purchased full coverage (or so we thought) through AutoEurope for a spring rental. When researching online, I found the same limitations as OP, and the Basic Plus plan still had a deductible of $1800. After reading so many complaints about EU auto rental companies charging for numerous minor issues, we just wanted the "freedom" of not having to worry. So, I called AE direct. The sales person said we could still purchase full coverage with $0 deductible, but only by calling. The charge was approx. $40 more than Basic Plus, for our 5 day rental.
However, after receiving our "agreement" with AutoEurope, the wording remained very unclear. So we called again. On the second call, we happened to get the same salesperson, who added "Did I explain the potential $2000 upfront cost". WHAT? I was both concerned and confused. I told him again we wanted the ability to walk-away without worry. Evidently, we are still obligated to pay up to $2000 for minor damages, but AE will reimburse (with proper paperwork and photos). That seems like a convenient out for AE. AND, we saw nothing like that mentioned on our agreement. So, still confused.
Can anyone else better explain?
