I had the word 'puto' scratched on my trunk by a former co-worker a couple years ago... other than that, no purposeful or accidental scratches or dings apart from the usual debris, though I live in a rather un-populated area.
Sorry to hear of your bad luck. They are probably just jealous or they assume an SVT to be a granny car like that thing they call the Mysteek or however it's spelled

I'd better go now, the beer is starting to work.
