Should I buy from CA?

Dear Hackrs, help a newbie. I’m looking to lease loaded Lexus RX350 or Infiniti QX60. But in my local Seattle area, it’s like even mentioning something like 10% discount off MSRP to salesmen makes them go on an attack mode like I did something utterly stupid and ridiculous. So do all these talk of 10-12% discount off of MSRP really only apply to Southern CA (or maybe other bigger markets)?

And if I want to get the car from CA, do I basically request for quotes at many dealerships and find what’s available and maybe let me them compete a bit? Thank you.

Get a written quote from California and ask local dealers to match.
