I park in a pretty packed train station every day. By packed, I mean there are days I will miss several city-bound trains because I'm waiting for surburb-bound trains to bring home overnighters who will free up some parking space. Even though it's extremely poorly managed space, I've never had visible damage that I can recall...until today. I noticed jagged pieces of my front drivers side marker lens had evaporated, and scrape marks had appeared on the fender and top deck of the bumper. I'm thinking it happened yesterday, I parked next to a larger dark vehicle that would be high enough to hit there as he backed out and turned, but I didn't find any debris around there. I walked around a little in the area I parked the day before, but my memory of something as important as where I parked last week is failing me...so I guess I'll have to scour the lot to find my lens, or pieces of it. This was our old family car that I took for commuting when we got the minivan. I had planned to sell it, and previously, the body was perfect with the paint in the beginning stages of fading. Dumb damage like this affects the psychology of the buyer and could kill the sale. Should I just eat this, buy a lens, and forget it? The lens is probably only $20. Or, should I try to find the location, and look for a vehicle with matching scrapes? This station is in a very affluent area, and most of the cars there are brand new, or at least have perfect body's, very few have dings and dents, so if I spent the time, I could probably find the perp. If I pursue it and find them, should I leave a note/reciept on the car with a photo of the lens damage? I'm wondering if I should even do a police report, I can't rememeber if I have collision on this car (point really being, is it worth just getting documented). On a side curiousity note, have you ever hit a parked car, done damage and left it?
