GARDX, DON'T WASTE YOUR MONEY
I purchased a 4 year old BMW with only 12,000km from the Auckland BMW dealership and was advised that they would organise the transfer of the GARDX from the original Chinese buyers to me, the new owner. Soon after, BMW Auckland contacted me to advise that I had to organise the transfer. So I contacted GARDX to arrange transfer. HOWEVER GARDX responded that I would have to get the original China resident owners to raise transfer paperwork to enable GARDX to transfer it to me and that the car would also have to be inspected to ensure that their Authorized Reseller, Auckland BMW had not incorrectly managed the car (such as applying a cut and polish) during their time of ownership.
If GARDX is trying to sell you their product by suggesting that you can transfer the benefit, don't believe them.
If GARDX is trying to suggest their product will value add your car for resale value, don't believe them.
Finally they had the audacity to try to suggest that I buy their entire system anew, because they would not transfer ownership.
VERY UNIMPRESSED WITH GARDX, WISH I COULD GIVE THEM 0 STARS.
