How to disable an E30? So it can't get stolen.

Put a tiger in it.

Tigers are expensive, cheaper route would be a cougar named Karen

Buy quick release , then take wheel and put it in the trunk they will never think to look in the trunk

No matter where you live NO ONE is going to try and steal an e30 by driving it away.
Now if they want it because its an e30 they may tow it but once again NO ONE will be driving off in an e30 without the keys.

If however you still feel like somehow you live in an alternate universe and there is a legitimate risk to getting your car stolen then do as suggested by pulling the fuel pump fuse or fuel pump relay or you could even unplug the CPS.

Honestly all that is a waste of time though.

Touched that up for you.

Never said it was the best. But it's cheap and at least it's a visible deterrent unlike the kill switch.

Unfortunately, if they want it, they will take it. It will just depends on how much they want it. At cheap, a blinking LED light on the dash will at least show an obstacle may be present.

^if you live near the reserve, they will steal anything on the main road that is old enough to hotwire. Then you can forget about getting it back because they use it for a impromptude demolition derby.

people steal E30s?

Removable steering hub- chances are if they walk up to it, and see no steering wheel attatched they will keep walking.
Instead of smash your window, destroy your steering column, THEN realize it wont start.

Trick switches and the like are only a minor inconvenience as compared to this. And, as stated, this is obvious. They'll know from one glance that they won't be driving the car away. That won't even slow down a pro as they'll most likely steal the car with a snatch truck.

My brother had a escort Mrk1 with a hidden battery kill switch.

Leave your car on cinder blocks and remove wheels wherever you park. I personally would put a switch on the seatbelt latch switch. No thief would put the seatbelt on, especially if they couldn't start the car they were trying to steal.

Get a quick release steering wheel
