Added (1). The incentives are based on the MSRP of the vehicle. So wasn't sure if it'll best to negotiate the MSRP down and then present the company incentive

It depends how the "incentives" work.

Id do it later. They still may try to tell you it was already figured in. They call it salesmanship. LOL

AFTER. OTHERWISE THEY WILL COME UP WITH SOME B.S. REASON AND SAY "ITS ALREADY FIGURED IN".
