Depends: If you want to go mod crazy, I would go for a 95 OBD-I car. I purposely didn't want a 10 year old M3, so I ended up with a 99 OBD-II M3, and plan to do a differential swap instead. Im not into turbo'ing/supercharging just cuz i fear reliability issues. Maintence on M3's is already enough as it is.

OBD 1 responds better to typical bolt on mods. OBD 2 is harder to make more power.

Do a search, this has been discussed before in more depth.

The best is a '95 with a 3.2 swapped in and converted to OBD-I. BSP legal with 300hp.

Actually the complete Conforti kit gets you about there without the switch to 3.2. That is CAI, Euro HFM, 24 lb injectors, and special software. About $1000. 297 or so.

The 3.2 does give a bit more torque down low though.

And yes, you can switch an OBD II car to OBD I, IF you state allows this. MD doesn't unless you have swapped the engine into an earlier car.

And converted car can have various problems, it is not trouble free.
