When picking up the car, the staff insisted that we buy insurance, despite us having full coverage purchased through a domestic rental platform. We didn't buy additional insurance from them. During the car inspection, the staff mentioned that scratches on items like the spoiler were not an issue and assured us of no worries, so we didn't take photos. However, upon returning the car, they claimed we had scratched the left side mirror and the tire, insisting the tire was new and required a complete replacement. She demanded £500 for repairs, with a potential partial refund after the repair but mentioned the process could take 1-2 months with email communication only. My objections were dismissed, and I was told this was the only way to proceed with the return, with a very firm attitude. The said damages were barely visible unless up close. Throughout my drive, I’m certain there were no scrapes, so I am very displeased that these damages were attributed to me. Despite having full coverage insurance, the rental company's actions left me feeling helpless and very unhappy. The attached photos show the claimed damages needing repair with a £500 charge, which is unbelievable, especially since the tire clearly shows wear and is obviously not new.
