...had the same obsession you did (saw my first Cobra at Watkins Glen, NY). Took YEARS to get one (I bought Jamo's Butler---which was the make I wanted). If I were you, I'd look at an SPF and compare...compare..compare. Another way to get a "turnkey" is follow my route---buy a used one until you can spring for the one you want. It gives you "seat time" (driving experience) and lets you see what you like (and what you don't). WARNING: you may not be able (or want) to "unload" your first car. I located someone who wanted me to buy and fix one up for him before I bought. I'm not sticking to one Cobra---although I will be doing it one at a time!! Good luck!
