I'd say why insure it if it's only worth R25 000? Just get a tracker at R168 per month, and everytime you fetch it from the recovery pound, pop a grand or 2 on your sound again...as it wont return with that...if it returns.

BMW525i - never insured - "re -sounded" twice - stolen/recovered twice in 4 years...worth R25 000. Totally yearly expence = R168 X12 + R2000 (Sound) = R4000 per annum.
