Exactly!
I doubt very much a Lexus dealer would give a loaner to an under aged individual.

 

last year when i was 20 and had to do my 5k service i went to westminster lexus and they wouldnt let me take a loaner unless i was 21 however they let my parents sign for it and let me take one (but my mom didnt want to drive down so i was stuck there haha) however, when i went to get something else done, i went to tustin lexus and they let me take a loaner anyway even though i was only 20

 

i just bring my macbook and type my essays and eat the munchies that they have at the dealership. :]
