Your friends are ridiculous. I am a long time silicon valley resident in your general age range and your friends sound like people I know who are shallow and all about image. Go to rich areas and notice the number of older and not so flashy cars. Even people with success to trump don't necessarily do it. Drive the car you want to drive, not what people think you should be driving to send messages to others.
The fit is a great car, if you want driving dynamics, cargo space and small exterior volume. It's practical, reliable, the gas mileage doesn't suck and the resale value is excellent (so don't buy a used one). Lets say you get a 370Z instead (I would put money that at least one of your friends has something like this - or a 350 Z or G35/37). You'll have a fraction of the cargo and passenger space, several times larger payments, higher insurance, close to half the fuel economy. Factoring in all the costs, including depreciation, you may be looking at twice the cost, long term. Is it really worth it, just so that you can send a message to people who may or may not be listening (or care)? Not unless you truly want that car.
Think of the car as another tool, like a fancy new lens. Sure there are lenses that give off an air of authority while being impractical and expensive. Would you go carry around a L series supertele just so that the first person who looks at you will think you're a hot shot photographer? It will grant you a "social advantage" (while being much cheaper long term than the more expensive car).
