Service satisfactory... had initial issue with car

Like: Pick up.. easy to find location.. staff was helpful.. They didn’t have the car I reserve... was offered a Vauxhall Zafira or a upgrade to MB E Class - I choose the upgrade for a reasonable price- Very comfort car to drive in long road trips.
Dislike: Car wasn’t clean inside or outside (I let this issue go as I have a very long drive ahead, the interior was dusty in parts and bird poop is baked by the sun onto car body and windscreen).. the car had a issue with one of its power window—- kept opening itself (so I need to drive back to rental office to have it fixed).. although the car had low mileage about 13,000 miles - the are signs of abuse within the car’s interior
