Is this a good beginner road bike?

Is this a good beginner road bike? I found it next to the trash just like that. I wish the racing seat was bigger it kind of hurts to ride but ive been told by the local bike shop I'll get used to it.
I know GMC pioneered their own alloy for the Denali so this bike should be lighter and faster than anything else out there. Also, you can sprint standing up with the grip shifters on the flat part of the bars no other bike has this.
