Hello,

I made a pay-later reservation at Hertz SLC on a Monday morning in April for a G4 (XTS or similar). I also made a pay-later reservation for significantly cheaper at Enterprise (same date and time) for a Premium car (Maxima or similar). Driving through national parks and returning to a different location in Arizona. The goal is to drive off the lot with something relatively interesting (Mustang, C300 etc...). I'm willing to pay around $30 extra a day for an upgrade - maybe a bit more at Enterprise and a bit less at Hertz. Does anyone recommend a strategy here? How late in the process can I walk away from the counter/which company should I go to first? Not a business traveler, so I have low status at both.

Thank you in advance.
