Been lurking here for a while, so thought it was time I signed up and contributed.
I collected my latest Hertz rental from LAX last night. Brand new Jetta 2.5 SE SportWagen. I found it in the darkest corner of the lot and the agent said he had never seen one before. It's classed as a YC.
Whilst looking around (something I also do!), I also found the following newcomers to the fleet:
Chevrolet Spark - amazingly, tagged as a B. This should be a pre-A car!
Infiniti JX35
Ford C-Max - at least one of which was a Hybrid model
A couple of Toyota 4Runners - been a long time since I saw those on fleet
I've got a few more rentals from LAX this trip (Booked lots of short rentals so I can try different things), so will let you know if I find anything else not already on the very informative list.
