Well I had my Golf GTI for just three days 20 mth old lovely condition with all the extras...stolen this pm when at my Gym
As others have said before me, we all feel for you.
I must ask the question, though - Tracker

??
...plus all my golf clubs etc etc.
Again, as others have said, fcuk the golf clubs! Does the Gym car park have any CCTV ??
...and no gap insurance.
Now this GAP insurance - I just don't get it. I presume you had fully comp insurance, then the insurance company has a legal responsibility to recompense you fully (less any excesses) in order for you to obtain an identical specced motor. With only 3 days of your ownership, there should be no doubt as to the value - and the fourcourt value is also vitally important regarding your "negociations" with your ins co.
As others have stated, post the full details of your stolen car - colour, doors, reg, VIN, engine no, location of theft - so we can all keep a look out!
