The important thing is to always be conscious of what people might think of you based on the car you buy. Nothing matters more than being perceived as cool by people you don't know. So you can't get the Lexus IS-F or your life will be ruined.
Couldn't agree more. Choosing a car for affordability, comfort, driving pleasure, or equipment levels is a complete waste of time. Nor should you bother yourself with MPG, running costs or future trade-in values. Your only concern should be whether or not people you don't know whose opinions don't matter think you look like a dork while driving it.
Meanwhile back here in the real world... if someone labels you purely on the basis of what you drive then my guess is that you want nothing to do with them*.
While there are a few cars that nobody can look good in, if you want to get an IS-F then go for it. That said I really wish I hadn't warned my last boss off the Lexus SC430 by telling him he'd look like a second rate pornographer. It would be so satisfying now to see him oozing about town with the top down looking like the fat, middle-aged sleaze he really is!
*With the caveat that we all know Audis are now driven almost exclusively by cocks, at least here in the UK.
