Buying my first road bike! Opinions needed please!

2011 Specialized Secteur Sport Compact on sale. It's a 49 and when I rode it I felt good (besides my butt of course) but I am barely 5'0".
TIA!

I would need to have a really compelling reason to show a woman rider under 5'5" a Secteur in size 49. Red flags flew when I read this.
Don't they have a Specialized Dolce in a 44 (or maybe 48) for you?
I have had really good luck with the 44 Dolce and 5' 1" riders. Occasionally I need to put a bit longer stem on it, but that's OK because the stock stem is about 2cm long.

PS uncomfortable "of course" is not acceptable for your backside. There are so many good options for saddles. Don't feel like you need to be in pain or "get used to" a saddle. I like the Selle Italia Diva Gel Flow, but there are many many opinions and options out there.
