Not Texas, but here are some good deals: Mercedes EQ deals - #349 by oarfish18
Specifically:
EQS580 SUV 36 MONTHS - 7500 MILES
MSRP 135090
3k drive off - 974 plus tax
3k drive off max msd - 851 plus tax
About $6K less MSRP, and these are 36 month (better program than 24m right now). So, not apples to apples. But you can get an idea.
