Surprisingly stable yet a bit too high.

Sellers:

http://www.tf2outpost.com/trade/22012015 1 Bud, young.

http://www.tf2outpost.com/trade/21096354 1.1 Buds, 1 month unsold.

http://www.tf2outpost.com/trade/21930296 1.1? Poorly bumped.

http://www.tf2outpost.com/trade/21809104 Seller wants 21 Keys for the Coupe alone as stated in the comments(1.1)

Sold for 1 Bud + 2 Keys(21 Keys)

1.3 Doesn't seem to happen, though 1.1 seems to be the more common trading point for now. Couldn't really find anymore sales.

1-1.1 should be fine as a conservative drop.

Additional Proof/Counter-Proof/Constructive Criticism/Feedback is always appreciated.
