It takes five minutes tops to put on the exhaust tip. Cargo cover even less.
Sorry for the mishap, and you should be able to trust a dealer, but I don't.
This is a prime example...
When I got my limited, I had them put the VIN on the contract and add the phrase "or identically equipped replacement".
They found the vehicle I wanted nearby, but it had the auto running boards. We agreed on an additional $1000 ($1500 option).
Good luck on your deal.
