Well the dealership with the New '19 3.8  Ultimate  for $39,999.99 would not budge.  You would think because they have 4 that have been on the lot over 267 days they would be more flexible.  They even added a BS  $995 "SWAT security system"  on top of the advertised price  that they would not remove from the price.  Also we were $1900 apart on my trade-in.   I texted them a counter offer of take off the "Swat" and split the difference of my trade in about $ 950.
I heard nothing then I thought about it.  "What am I doing?  My initial plan was to get a used '17 G80  with an sunroof between $20k - $25k.  It would be my first Luxury car.  I liked the "17 but, 
Android auto in the '17 Ultimate.  So, I wanted the a '18+ and I pushed my budget to $30k.  So, why was I working so hard to spend $43k on the '19?  I thought the V8 was ok but the performance didn't warrant the extra price in what I was looking for.
After not hearing back it gave me time to think and I pulled the trigger.  I bought a '18 G80 5.0 Ultimate from Carvana for $31,900 with 33k and  35 months/ 27k left on the basis warranty.  The miles are fine because I only put 17k on my Volt DD that I have taken to Vegas and Palms spring from Los Angeles.  I only have a 20 mi round trip commute.  It was also the cheapest in the nation when I checked CarGurus, autotrader, etc...
I get  it from the vending machine next Saturday that is 15 mi away instead of driving 233mi to Fresno.
Thanks everyone for all the information
