The nicest Puma is on the Samba is in Oakbrook, IL Exceptionally low mileage, HP motor. I have seen it in person. You didn't say though what years you were thinking about, or whether a hardtop or convertible.
I have a 1985 PUMA GTI COUPE for sale. I've rebuilt the motor including heads, carbs, etc. I've replaced the tires. It has power windows but unfortunately my EX decided to disassemble the motor/mechanisms and I don't know where the parts are. I get my parts from "PURRING PUMA'S", I do have a parts list with approx. cost to replace those parts and the inner door panels. The seats need to be redone (hard to find seats for sale).
I bought my Puma from Jorge (House of Pumas) I'm only asking what I paid for it so my what I invested is my loss. Let me know if interested. Asking $5,500.00. Yes it does run. It also has a moon roof. I replaced the windshield/seal also.
