Whilst the car is in the shop, get the cooling system overhauled, since you don't know when it was last done.
Carfax can let you know where the car was registered by the POs. You can write to those states' DMVs for the records on the car. You may be able to find their addresses, and contact them for maintenance info. That's how I found my PO.
You probably didn't get the owner's manuals and zipper pouch, nor all four keys. You could ask them if they still have them.
Dealers have no vested interest in giving you the service info.
