So, I am in the process of buying a new car, and one of the things they asked me was if I wanted to get the VIN # etched on all of the windows for $299. They mentioned that this would save money on your insurance. I declined for now, and decided to do some research. So, apparently putting the VIN # on the windows acts as a theft-deterrent. Since Police use VIN to find stolen cars, if someone were to steal your vehicle they would have to replace all of the windows. Most people stealing cars know this & it makes your car less attractive. I found some DIY kits online for about $20, but I don’t want to link one in particular yet because I haven’t researched which one is the best. The best part is that doing this will save you some money on your car insurance as it’s an anti-theft measure! Just passing it along in case anyone else didn’t know!
