What is the difference between the phrases?

Question

Google Ads

Hello!
In the settings of my advertising campaign, the display region is Moscow, I'm wondering what is the difference between the two requests.
Let's say the user's request is: Buy a car in Moscow
My keywords:
+ buy + car
+ buy + car +
Moscow + buy + car do you still have?

Answer 1

The stakes and competition will be different. Leave both keys, minus "Moscow" from a wider one, see how it works.
It's faster to test than to ask here.
More broken words work better

Answer 2

well, if you are ready to pay for buyers from Barnaul, then there will be a lot of even cheap traffic
