I can't believe a Lexus dealer would do this. It's one of the reasons I'm back with Lexus, the dealers treat you like Royalty.
I've had interactions with three Lexus dealers in the past (Sheffield, Manchester and Stockport) and all are top notch.
One occasion which springs to mind is when my GS300 Sport went to Sheffield for a service and for them to fit a new electric aerial as I'd snapped it off. I drove there from Manchester and forgot to give them enough notice to sort out a courtesy car so I expected to wait in the showroom whilst they did the service. When I got there the service manager said "Here are the keys to an RX, go and take your missus shopping". So off we went in a brand new RX. When I got back they said service went fine no faults and it was only about £180. Then he fit the new aerial and when I asked how much he said "forget about it - no cost".
Just brilliant service. Not long after I sold my Lexus but that has always been in the back of my mind and now I'm getting a Lexus again.
