Depends on what M240i model year you’re after. In the newer ones (2022+ model year), they’ve updated the interiors to at least match the rest of pre-single screen (anything before 2024 model year) lineup, so you might find something you like.

As well, it’s important to be realistic with your costs too, for both your and your wallet’s sake. I obviously don’t know your financial situation, so it’s difficult to suggest what vehicle you should go after, but I’ll give you some advice based on how I purchased my vehicles: if gas and insurance costs are things that you have to think past “which account are they coming out of”, then you probably shouldn’t get the car. Horsepower should only be a dealbreaker or significant factor once you’re clear of the financials. You’re better off with a full wallet in a 2-series than an empty one in an M car.

That being said, I would shop around for something certified pre-owned so you needn’t worry about maintenance for a while, that way you can put all your purchasing power into the sticker itself. Also, don’t be afraid to search for vehicles a little further from home as well. Far places (road trip length) can have great rewards, and you get an opportunity to bond with the vehicle from day one.
