For your purposes, a 2016-2018 M2 is a far better fit. Running costs will not be more expensive has it's just a tuned N55 with a highly desirable oiling system which is far better suited to track driving than what comes in the M235. You'll spend nearly the same money to get a modded M235 to perform like a stock M2 on the track and even then, the M2 will be more composed, connected, and consistent plus you have options to make the M2 even better with wider rubber with no clearance concerns. The M2 has a far better LSD than the ones available to the M235 and the M2 has the M3/M4 front and rear subframes which are better in every way from a performance and dynamics perspective. So either save up for the M2 or dump money into the M235 and just accept the fact that it will never be quite like an M2 when it comes to track driving.
