The last loaner I had from Infiniti was a new M37....it was sweeeeet!!!!
Still, a bit big for my taste.
Didn't think the wife was going to let me return it!!

She loved it.
Got to admit my fanny enjoyed the A/C.
The time before that was also a M37. (was this summer)
Got a Cube loaner at my Nissan dealership when I had the G coupe checked for some warranty work a while back. Daughter loved them at the time, so I thought what the heck. I think they are the best looking box on the road, but I didn't care for driving the thing at all.
All of the loaners that I've received were gassed, cleaned, and had no smell of smoke or animals.
