It becomes non-refundable when you sign the paperwork for the actual build. The initial $2500 deposit just gets you a place in line.Not to beat a dead horse here but the dealer has sent me a bill of sale and requires the $2500 deposit. It doesn’t state anywhere that it is refundable. What have you seen as far as paperwork stating the deposit is refundable? At what point does it become non-refundable?
