Would you really want your car back after its been sha66ed by some dirty little theif???
This has been discussed many times before on this very forum.
However, as a recap, there are loads of advantages of having a tracking device fitted, against just one disadvantage.
Firstly, the disadvantage, which you rightly point out above -
if it had been abused by a scrote, then no, I wouldnt want to keep the car. However, the days of the general opportunist thief are long gone. Most modern cars which are stolen these days are either (a) stolen to do a bank job, which means the car will probably get trashed anyway, or (b) stolen "to order" by professional gangs of thieves for the purposes of selling them on, and so these will not get trashed!
Now for the advantages:
- Cheaper insurance (indeed, many insurance cos make it mandatory for certain high performance cars)
- The Police will catch the crims red handed, and they'll get locked up
- You wont lose your no claims bonus
- You wont have a "total loss" claims history, which will massively bump up subsequent renewal premiums
- You wont get any future revisits from the crims in 6weeks time to collect your new car too
- If your recovered car is damaged in any way, it is considerably cheaper for the insurance to repair it rather than pay for a write off claim
- If you are uneasy about keeping your stollen recovered car, then YOU can sell it in your own time, at your own price, rather than relying on an undervalued insurance settlement (and you wont have to drive around in a Nissan Micra courtessy car either!)
I'm sure there are a few other advantages, but AFAIC, getting a Tracker fitted is an absolute no-brainer!
