Sorry to hear about this bro . I had my GTS- T stolen about two years ago. Thank god the police found it in Broady, LOL. The police are useless in finding them. If it turns up . Mine was stripped of many expensive parts but they where really dumb and left the most expensive stuff. Anyway here's some advice.
What mechanics have you taken your car too and did you give them your address, ( lots are heaps dodgy )
have you bought spare parts of someone and told them your address
have you noticed anyone following you.
maybe even someone at a shop you bought something from.
also i hate to say it mate but often it is someone that knows you., so start asking your mates.
Can i just say those parts will end up back on the market most likely. Buying parts off sus people or buying parts that you know are stolen is contributing to the problem. It feels okay when you get a bargain , but when your car gets stolen i guarantee most of you will never buy a stolen part again.
i'll keep a look out bro
I know how it feels
