I'm 50 and I get alot of the "mid life crisis" jabs but I really don't care. I bought a 350z in 05 and now I've got the 09 370z and I have zero regrets.
The 350z sold in 3 days too, when I bought my 370z. So they are very popular cars and hold decent value compared to most.
Never worry about what others think you should be doing (outside of maybe your spouse of course). If you can afford it, you are the one that has to drive and maintain it. So buy what you want and have fun. Simple.
