What Am I? Bottoms Up

Welcome to another edition of DT’s cure for the Monday morning blues — What Am I?  In this better than riding on the bus game

we find a random picture of a car and you get to guess what it is. Last
week, the picture of the footwell of a low mile MX-5 was instantly solved by a reader.  Today’s WAI feature is going to be harder.  Just what am I anyway? Update with answer below.

Guess away.  Comments below.

A few sharp eye’d readers immediately suggested Pontiac and Fleetwood T Brougham got really close with his guess of a 1961 Pontiac Ventura, but RyanM solved the puzzle by linking to this 1962 Pontiac Catalina currently bidding for $13,100 reserve-not-met with 6 days to go.  Great work guys!  Last thing — the Q&A section has a funny exchange with a buyer, read it for a laugh.

A: I am in MO, but it
doesn’t matter for you. I have blocked you from bidding on my auctions. I
don’t care for guys that put in bogus high bid amounts then cancel them
just to get the reserve amount. I also do not like guys that add
pennies to their bids. Kind of childish and weird to me. Have a nice day
