The Vixen!
I'm 35 and your wife has cut me deep.
I plumbed for a black FSport with the chrome alloy and spoiler upgrades and they screem "i'm not old", as well as some other less wanted things perhaps. I love my new IS!
Yesterday morning I caught my wife looking from my car to hers (15 plate E-Class, also black with sporty wheels) and back again. I asked "whats up?" half expecting some trite remark about Mercs being far superior, blah, blah, blah. She looked at me with sad eyes and responded "your car makes mine look outdated". Victory!
My point?
The new styling of Lexus cars, which is gradually being introduced, will drive down (no pun intended) the average age of it's clientele by some margin. Obviously due to affordability reasons Lexus will not be engaged by buyers in their early twenties but, I am confident that there will be a concerted shift from cream interiors to black over the next few years as the vehicles look more and more cutting edge.
Well played Lexus, you have won back my business!
