There has to be a "voice" for a company and I think that James Sloyan did an excellent job. It conveyed the elegance and subtle luxury of Lexus without being pompous or arrogant. You can't put a "Mitsubishi" type commercial for a Lexus, because it just would not work.
Hey, I dabbled in marketing for a little while and it's all about selling a perception, not necessarily a product. I guess the bean counters figure that it's time for Lexus to move from "old folks" to "young folks" range since Lexus owners now probably buy only one Lexus because they'll be dead before it's driven to the ground. Should get younger buyers so that they might live long enough to buy TWO Lexus' in their life.
I look at it this way, would Disney decide "hey, Mickey's voice is too boring, let's replace it was Ahnold Schwar's voice !!!"
'10 MDX blk/blk
'04 LS430 CL blk/blk (I'm on cloud 9)
'99 RX green/beige - (still smashing, but it's the beater)
As I said, right at the LS demographic, but not for the damned IS!
Funny that, now that Lexus has taken your advice and replaced him, his first radio ad is trashing the IS-F in favor of the Mitsubishi Lancer Rallisport. Apparently Mitsu thinks that his voice can appeal to a younger demographic...
