Yes you should. I've had 4 or 5, I think 5, MX5 daily drift cars now. Best ones as dailys, as you can abuse the shit out of them and don't break. Only once have I not made it back from a drift day in one, and never had an issue barring that aside from when a radiator burst on me, and I still got it home.
If you can't skid a standard engine 1.6 MX5 in the dry even on the biggest roundabouts in the world, you need to take a step back and have a look at your driving.
