2011 cannondale caad 10 4 - Good Deal?

[reux]

Hello Everyone,
I'm pretty new to cycling but I fell in love with it from my first ride. I currently have a nice hybrid bike that I love but would really like to get a road bike. I figured since it was my first road bike I shouldn't spend too much so I've been watching Craigslist.
I ran across this bike today and of course it's $500 more than I had planned to spend but I checked out the reviews and think it might be worth the splurge. The guy says he spent $2,000 last April and was asking $1,300. I offered him $1,000 and he responded yes immediately (darn, should have started lower!).
It makes me a little nervous because he is so eager to sell it, plus I really didn't want spend that much. I still have alot of other stuff I need, like more shorts!

Here's the ad (notice he doesn't spell caad right, craigslist makes me paranoid lol):
I have a cannondale cadd 10 4 for sale. It has sram rival components. I put only 500 miles on it last year. It's a size 52.

His pic is below but the images that come up when you google it are gorgeous!

So, I'm really nervous but excited about this bike. That little voice in my head is yelling at me for spending a grand. Especially since I know so little about bikes. I would love everyones opinion.

Good bike/deal, or not?
