Hertz - YVR and Upgrades

I'm currently in YVR and am just a plain ordinary gold member and don't mean to look a gift horse in the mouth but...I booked a Compact with Hertz and since it was late when I got in to YVR I didn't think about it the car or much of anything else since I had be travelling for the lst 12 hours and just wanted to get to the hotel and crash. The Gold desk in YVR offered me a an upgrade to an F150 pickup, which I declined. They then gave me the key to the Chevy Impala they had the paperwork ready for.

First question, since I booked a compact, do they really consider a Chevy Impala a compact or did I get an upgrade? I would have thought a Cavalier would be more in line with a compact.

Second, if I did really upgrade is there any way to make sure that you get a car in the class you actually booked? In this case since I'm driving in a city I like driving in a smaller car...easier to park, etc.

The Impala is a specialty fullsize (between Fullsize and Premium) You came out real good on this deal. ^

I just had one on an F reservation (I know, should have been given a premium but the Impala is much better than a CV/GM) but it was PURPLE with tan interior.

They are notorious for trying to give away SUV's to people as upgrades when they are out of cars at this location. In Canada an Impala is a Full Size only, not a specialty like it might be in other places it sounds like they gave you a double upgrade as no smaller cars were available.
