What year should I buy? 340i

I think it’s time for a new car, I’ve been driving a 08 accord for 4 years now and i’m finally tired of it , anyways i was looking into getting a 340i but I just wanna know what year and package / mileage I should look for, any help would be great. The dealership down the road has a 2017 with 62,000 miles on it and 3 previous owners with a clean title.
