yes. apparently they can only keep open invoice car for a month. they have to get rid of it before new month starts. so end of the month they will offer low price just to rid of it. start of month they will not accommodate low own.
my variant is aspire cvt modern steel. paid 50k. mentioned color cause white and silver are the most running color so maybe low own because of color. but i paid end of month. i could probably have negotiated lower too. they said 100k i said i can only do 50k and instantly agreed. so maybe there was more room.
ofcourse yes it varies city to city also dealership to dealerrship. but 2 of them offered me 50k. but again both end of month. they didnt offer me 50k when i first enquired which was middle of the month.
