I don't recall being shocked by any car (Delaware), but that doesn't mean I never was, I just don't recall it. On the other hand, I'm pretty sure I've never been shocked by my xB2, and I don't think either by my 1990 Eclipse. I'm thinking the idea of using something metallic (a key) to ground yourself before directly touching the car may be a good idea. I know fur and perhaps wool can generate charge, but typical cotton and polymeric materials are usually safe.
