$4000 would be a good price. I have seen a lot of themn for around $6000. It sounds like a winner! These cars can develop expensive problems so be prrepared, just in case. My Euro 500 has eaten up $7500 in parts alone without the steering box, a new top or A/C that could all use replacement. I do all the labor (with love) and tend to replace old body rubber at the drop of a hat. I still need to do some body seals and a lifter or two. I have 125,000 miles and drive it year round. I have snow tires on it for the winter. Good luck.
