The store suggested additional costs like insurance upgrades and fuel charges, which I identified and declined, but I almost fell for it. The RAV4 I booked was unavailable, and they gave me a KIA SPORTAGE instead. They claimed it was the only car of the same type left, which was confusing... The attendant at pickup told me I only had the basic insurance and needed an upgrade. I said the car rental platform I used already included comprehensive insurance, so no upgrade was necessary. He said okay, there would be no extra insurance charges. Then, he printed a paper and asked me to sign, emphasizing with a pen that the charge was zero. But I noticed the total amount was $56. When I asked, he explained it was for fuel. I told him my agreement with the platform was full-to-full fuel policy. He insisted their option was cheaper than refueling myself. When I insisted I didn't want it, he quickly crumpled the paper and threw it away...

The return address was unclear.

To be honest I would have expected better from Europcar, It was a franchise they used, staff were helpful especially at pick up area. The outside of the car was clean the inside was just about tidy, Front window was very dirty on the inside had not been cleaned in a while, no water in the washer bottle had to fill up myself, every so often a message would appear front sensor not available you would assume that this is checked and attended to before it went for rental,

only1 person on the advantage car hire desk took nearly 1 hr to get the keys etc

Europcar were unable to tell us whether we would receive a 4WD/AWD car before picking up. They also don't fit cars with winter tyres (despite us requesting them). Both of these can be made a legal state requirement to drive on Colorado roads during winter storms, as happened numerous times during our trip. It was only through luck that we received a 4WD and so could get by without proper winter tyres. This is a huge safety issue, it's crazy to be sending people out driving on Colorado roads in the middle of winter without winter tyres.
