When buying a sports car, you're not buying the car out of necessity, you're buying the car for joy. If you're not 100% into it when purchasing the car, you probably shouldn't have purchased it, IMO. Cars aren't exactly a cheap purchase, so you should be sure that the car makes you 100% happy. I don't care what car reviews think, what your friends thinks, its how you feel when you stare at your car or when you're cruising around in it.
Walking up to the car, you should have the smile on your face. I have that with my 370z because when I purchased it, I knew exactly what I wanted, no more, no less and it fulfills my expectations out of a sports car right now.
I do admit, I love it more now that I have the engine broken in and I can actually enjoy the car. That first 1200 miles felt like hell, not being able to put my foot down on that throttle. Now that its good to go, man, jumping on the highway is fun fun fun. The manual says to keep that needle at under 4000 rpm pre-break in....4000rpm is really where the fun begins, so who knows, once you get that sucker alive, it may show you a different side you haven't experienced yet.
Everyone's different however. Some folks are the "grow to love it" types and some are "hate it/love it right away" types. I'm the latter. If it doesn't suit me right away, its rare for something to grow on me. I may get used to it or tolerate it, but I'll never grow attached to it.
And if you're drunk, then maybe you just need to have a few more beers and think about it a little more
