Audi A4 2002

I am selling my Audi A4 B6 Cabrio with the 2.4 V6 engine. The car is a second-hand purchase. It comes with various previous owner invoices. Oil change was performed 4 months ago. The roof operates smoothly. Air conditioning does not work, possibly due to gas issues. Transmission is automatic. The vehicle has 136,000 km on the odometer. It was last registered in Neuss on March 3, 2002.
