Rest assured that Mercedes never provided me with a G-class loaner and the loaner that was provided was always a "no smoking car" (a perfectly reasonable policy IMO and fine with me since I have asthma and don't smoke). Their loaners were Mercedes vehicles, but ran the gamut on the model - sometimes a C class sedan, sometimes a GLS. Most of the time, I ended up with either an E class sedan or a GLC. Same thing when I had the Lexus LX-470 a while back - the loaner was always a Lexus, but never an LX. But having SOMETHING to drive for the day or so the car was in for service was the important thing; I don't expect the get the exact model I own.
We have owned a lot of Mercedes and Lexus' over the years and have dealt with the service departments extensively.
When talking with the people in the service departments it always amazed me how the Lexus waiting room would be filled with miserable looking folks eating and drinking their FREE stuff while they got their FREE carwash.
We typically would drop the car off on Saturday and tell then to take their time, Mrs. has to go shopping all day...
They would generally call her cell a few hours later on the way home and we as always leave a nice TIP for the cleaning crew.
One day it came up ay a closing time chat how much and how many people tip the crew....
It turns out only a handful of these FREE carwash, FREE food & drink Lexus owner's tip the crew...
The staff at hotels, restaurants, car dealers any service industry, etc. work hard....
They are not dumb or blind, they know who you are....
It's amazing what you get when you spread around some $$$ and praise the good work being performed by the crew to the higher up types...
Ain't got no problem there... no how...
BYW, We have recruited a lot of good employees this way too...
Additional thought , "Land Cruiser" should be a special brand offered at qualified Lexus dealers, like Maybach is to Merc.
