Welcome--the Z06 is a solid pick for that price range. That being said, if only going VERY fast, instead of SCARY fast is enought for you, I'd look in the 30 range (plus or minus) and have some cash for some mods down at Manny's place.
Also, if you like old iron, you can probably find a C2. Whichever route you go, you're going to make the right decision. If you have 50k to spend, and want to go newer, I think most people would say go for 2005--or even 2007 and up. Stock C5s were an awesome step forward, and the C6 made another great jump in HP and performance.
Any way you slice it, you're going to love the 'Vette world. Welcome aboard. Post some pics when you make the purchase and stick around! Welcome aboard!!
