My Lexus dealer has been great (Pohanka, Chantilly, VA). They're open 5am - 11pm and appear to have many technicians working throughout the day.
Oil changes and other small services are done while I wait and do NOT require scheduling ahead of time. They have a large lounge with food/drink, TVs, wifi, and a quiet office space for work.
Larger services have always had a loaner car included. It's always been a current model year Lexus RX. Again, no call ahead, just drop it off and drive away. The longest they've taken is a Sunday PM return on a Friday PM drop-off.
