I agree with the ISF not being that fast, a few mods will help but like anything else you get use to it and will want more power...
Stock 0-60mph in ~4.5 seconds? Stock quarter mile in ~12.8 seconds? Stock tire ~70mph slalom speeds? A constant pull all the way up to 160+mph? For a stock road legal car, this is fast by any definition of the word. Any sort of performance advantage a competing car may have (C63, M3, RS4/5, CTS-V etcetera) is marginal at best in comparison. You would have to upgrade to a six-figure supercar to get an obvious performance difference. Your sense of perspective is a bit off.
The price seems a bit high to me. But with that said, you can't take the money with you when you're gone, so you might as well spend it while you're here.
