You've heard it said that if a professional car thief wants your car, he's going to get it. That's true even if the car has a burglar alarm. A competent thief can find the alarm and defeat it.
There is a new anti-theft device on the market that stops the professional thief by stopping his reason for wanting your car. In most cases the thief can't make money on the car unless he can change its identity.
It's just like a kid carving his name on a baseball glove. It doesn't make the glove any harder to steal, but it makes it easier for the good guys to get it back.
The VIN is on a plaque, usually on the dash. The plaque is easily removed. Etched windows are another story ....
NATIONAL AUTOMOBILE THEFT BUREAU:
A vehicle extensively damaged, burned, or stripped, and in a condition beyond repair, is normally classified as a 'salvage vehicle'. On the legitimate market, the vehicle's value maybe limited to the value of its parts.
For a criminal, however, the value of a 'salvage vehicle' rests in the vehicles documents or in its identification number plate. The criminal will purchase salvage vehicles in order to obtain the certificate of title and the vehicle ID numbers. The criminal does not want the salvage vehicle for parts or scrap metal. Instead, the criminal uses the certificates of title and vehicle ID number plates to disguise and dispose of stolen vehicles in the legitimate market by substituting the title and vehicle ID numbers of the salvage vehicles for those of the stolen vehicles. This operation is known as the " salvage switch ".
WALL STREET JOURNAL:
Police say that one of the most cost effective security steps is having the vehicle identification number etched on each window.
NATIONAL WORKSHOP ON AUTO THEFT:
The public image of the auto thief is that of a youth who steals a car for temporary transportation purposes - that is, of the 'joyrider'. This image needs to be overcome. Nowadays, the typical auto thief is apt to be a professional criminal who is a member of an organized theft ring. Such rings steal automobiles in order to strip the vehicles major component parts, or to sell the car to unsuspecting buyers after altering the vehicle identification or to export the vehicle overseas.
CAR DEAL " INSIDER " NEWSLETTER:
This device does not prevent break-ins, but makes a stolen vehicle easier to trace and reselling a stolen vehicle an expensive proposition. An individual ID number is permanently etched into each window, sunroof and T-top. Rather than face the need to replace all the glass, a thief would choose to steal another car. In France and Great Britain, where the device is being used, the loss of engraved-glass cars has been reduced dramatically, 95% in France and 9 out of nearly half-million engraved-glass vehicles in UK.

According to investigators, a car thief might receive $100 to $500 to steal a car. A 'chop shop' operator takes the car apart and might receive $500 to $2,500 for selling the parts to body shops, depending on the condition of the goods ....
Investigators and law enforcement authorities, on a daily basis, locate components which by their characteristics are obviously products of chop shop operations, but they can not identify the parts stolen, it's nearly impossible now to trace a lot of the parts. There's just no positive identification and it's tough to prove a case ....
