I am also with SG Fleet - seems I am lucky and got a 'good' contact there as my experience has been really good (though haven't reached the 'pointy' end yet so we shall see). They told me it's very common for the Tesla invoice to be wrong to start with, Mine has been updated 7 times by Tesla, but we're good now
. SG Fleet require the amounts in the payment summary on page 2 to be the same on the left and right (Payment Due & Balance payable). For a Victorian this will show a $3350 refund to customer on the right hand side - the initial order fee and the EV subsidy will be refunded back to us once the sale is finalised as SG Fleet need to pay the full amount.
They are also not being totally honest with you about the FBT exemption - they are providing new quotes to new customers without FBT. They also refused to update mine, said all existing customers would be recalculated in Feb. When I pointed out one of my colleagues has a quote without FBT they said ok and updated mine...
