200-250k and then the timing chain needs to be done. It's a bigger endeavor than replacing the timing belt but it's not the end of the world. I'm not super familiar with the m42, but I don't know of them eating bearings or randomly shooting pistons out of the block or anything.
If your e30 runs bad, switch to Megasquirt first. Then try new spark plugs, cap and rotor, wires, oxygen sensor, crank shaft position sensor, coolant temp sensor, air flow meter, idle control valve, throttle position sensor, digital motor electronics unit, harmonic balancer, fuel injectors, engine harness...

it depends how well it has been looked after.

You're right, that is definitely the most correct answer.

If you don't buy it, I want it.

Make sure you drive the car long enough and you are ok with the lower power. It's always nice to have the extra punch of the M20.
