Please help a tourist - added photos and estimate

From the evidence presented here, it's my opinion that you're getting ripped off.

The other question is, will they take your $1100.00 and actually repair the damage? I doubt it. I've seen those rentals and many times they're pretty dinged up. Then again, I guess that it would become their decision to do with whatever they wanted to with the $1100.00. I doubt that there is any legal requirement for them to actually repair the damage once they charge someone for the cost to repair.
