Are dealerships still charging msrp on the 2019 GT63 and GT63S or are they discounting them yet?

All over the map.
My dealer has a Blue Magno with $197k MSRP, 400 miles available for asking $179k.
Test drove it on Tuesday along with S63 and M760i and was offered that car for an even $170k.
I was extremely impressed by all 3 cars, GT63 was a little bit too fidgety and tight considering my needs and Chicago horrible roads, the Supersports beat me down enough already.
BMW and MB are very, very close but the latter has a slight edge (I can easily modify it).

Taking delivery of Iridium Silver S63 tomorrow.

Was actually wondering if dealerships were discounting new GT63/GT63S?

There are some crazy holdovers sticking with premiums over MSRP but most dealers are trying to get full price, at least until you get really serious about the purchase.
Push come to shove and they will deal, car is new and "hot" but overpriced for what it is.
