Here's my $0.02: "A penny saved is a penny earned." I understand your rationale, but I disagree. I can't justify spending almost 3 times as much at a Lexus dealer for the identical service from a Toyota dealer - it would be different if Lexus wasn't Toyota, but they're the same corporate entity. The Lexus "amenities" are nice - Starbucks coffee, USA Today, PC access, HDTV - but since I already had them before I left home, they're worth zip to me. Plus, my Toyota dealer is more convenient, being much closer to my home. The Lexus service might be worth a 25 or 30 percent upcharge, but 267%? Not in today's economy. If Lexus is to survive on their non-warranty service, they need to be more realistic and competitive.
"it would be different if Lexus wasn't Toyota"
Why do you really think LS is just a Toyota... If so you need to get educated this will get you started.

If only Euro automobiles had the same standards their forums wouldn't be filled with service problems.
