I got a deal for a used Mustang in Canada at 7k. It's 2012 mustang v6. It's driven around 150k+ km.
I'm not sure if this should be my first car. But I really like Mustang.

I want to get a suggestion about if I should go for it at 7 CAD or not. I've seen a YouTube video that 300hp is good for daily driving. Mostly I will go to work or ride around when needed.

What should I check for? And what milage should I expect?
