It's expensive. So, FWIW, buy a car that's really reliable and parts relatively inexpensive so you can spend your money on track time and not the car. I have an F80 M3 dual purpose car and would have got an older dedicated track car (E46 maybe) if I ever got to do it all over again.
I doubt I'll ever get to Nurburging, too far and too expensive, but I've had a lot of fun on some relatively small and simpler tracks. Turns out I like the skill needed and experience of nailing a turn more than I like raw speed on a straight.
For Bimmers though my friend wants to get an M4. Oh and one of my friends gutted his old Bimmer, bucket seats inside that was crazy.

For the Exige above just the racking and down shifting sound, blip the throttle damn love that, that's why I'd never get an electric sports car even if it is faster, though the C8 can do a sub 2 second 0-60.
I've been passed on the track by cars with hundreds of horsepower less with a better track setup, lighter, and with better drivers.
There are reports of people taking EVs to the track but they are usually hampered by charging availability and heat dissipation. I've also heard that braking can be a challenge because you want to use regenerative braking as much as possible but that can make the braking unpredictable. The last thing you want coming in hot on a corner is to have any doubt about how well your heavy EV is going to shed speed.
I don't know for sure, but I'd make an educated guess that the EVs are really hard on tires. Lots of torque and relatively heavy is a bad combination for tire longevity.
The other problem EV owners face is that tracks have banned them due to the fire risk in the case of an accident. The tracks aren't equipped to handle a large LIB fire.
