I've watched as too many people, mostly kids but not all, lean up against my car (with the top down especially) and slide back and forth looking her over. Most recently at Tate the other day. ( A shopper, not a DCMM member )

I'd like find a good alarm shop. Ideally I'd like a proximity thingie that just gives the warning beep when some gets REAL close. If I can do that and disable the full siren even better, and just have it arm when car locked without a extra fob. Don't want to make a racket, just discourage people with belt buckles from leaving lasting impressions.

Suggestions of systems and retailers?

Thanks in advance,
Mark
