Yeah, every dealer does it differently. When I bought my Tacoma, I had it back the next week for issues I was having (see previous comments about 'that's what they do'). The dealer will give loaners, but only after they establish you have a warranty issue. They told me, seriously, that they could courtesy shuttle me home and if they determine I have a warranty issue, courtesy shuttle me back for a loaner. I could, however, 'rent' a loaner for $30 per day, but if it turned out to be a warranty issue, would only comp the days the truck was considered 'under warranty'. This is from a dealer that just 5 days prior I bought a new truck from.
The flip side of that, I bought a used Mazda (not from Mazda) which was still under warranty. A digital screen started flickering and I took it to Mazda to have it looked at. They gave me a loaner on the spot. They called me a day later and said that it was fixed, but could I leave it for a few more days, as they identified some other possible warranty issues. When I picked the car up the dash was fixed, the front seats reupholstered, the shift boot replaced, and some other things I can't recall. It made a big impression on me. I bought a car from their sister dealership next door.
