That does look pretty high.
I am seeing a 2017 GLI with MSRP of $30,235 for $298/Month for 36Months/12K Miles with $1,463 due at signing (First Month, DMV, Doc Fees, Acquisition Cost) on Honcker in NY/NJ.
Even when factoring in the $1,000 not paid due at signing, this should only increase the monthly payment by approximately $27~$30.
