What did I stumble on to last week?

Where I work there is road construction all around my office. So I have to take a detour through a neighborhood and this beauty was sitting under a car port just begging me to take a pic and post it.
I am a 50's/60's custom guy mostly so I dont know much about these cars, but I still think they are cool. What is it?



Sorry about the crappy cell phone pics. I didnt want to go up in the guys yard.

 

A picture would help.

 

Sport coupe? 28/29?

 

30-31

 

30-31 Sport Coupe, looks more like a 31 by the grill inserts
