RARE bubble window Isetta. Older amateur restoration included new engine, brakes, tires, and interior. All glass, including giant rear window, is flawless. Exterior paint has a few nicks and touchups but otherwise looks great. Sunroof in good shape, locks and folds back properly. Car starts and runs. New battery in 2018. Horn doesn't work; otherwise no mechanical or electrical issues.
