Not bad

I had reserved a Jeep Grand Cherokee, but upon arrival at the store, I was told it was unavailable. I was offered a Hyundai Santa Fe instead. Wanting an American car, I paid extra to upgrade to a Ford Mustang and specifically requested a V8 engine, which was confirmed. However, I received a convertible model with a V4 engine. Had I known it was like the domestic version, I wouldn't have paid to upgrade. I felt misled by the staff.

It was alright, nothing special.

The process was straightforward.

Returned and picked up the car at Auckland Airport. Small airport with fewer people and even fewer cars to choose from. The so-called 'free upgrade' is basically based on luck; you get whatever car is available. I didn't encounter any Chinese service, but my English is fine. Both pickup and drop-off are self-service, very convenient and straightforward.
