Car alarm mechanical not electronic needed....

Hi trying unsuccessfully to find an old style mechanically operated car alarm where the slightest movement would set it off, which used to be a real nuisance years ago if it was a windy day or someone bumped into the car accidentally. However it's needed for my 1983 Audi 100 GL5E that will be kept in storage as by passing electronic ones are much too easy these days. I think they were based on a simple pendulum that would go off when moved but drawn a blank so far so could anyone recommend where to find one ?

Thanks

Not sure if I'm missing something. The sensor part (trembler / tilt switch) is distinct from the (de)activaiton mechanism (key switch or electronic remote) isn't it? So a key switched or proximity deactivation would be OK with modern interior sensors wouldn't it - unless you see wheeling / lifitng it away as the main risk.

Thanks. No expert on this at all but I would have thought so yes however I was thinking that the less electricals the better. In other words gently shutting then locking the door without the alarm going off, then rocking the car hard to make sure it works ok as the garage is at the side of the house....

Thanks for the link looks ideal will check it out....

Selmar were the original trembler type car alarm I think.

Yes, Selmar... I fitted my first in 1981. Your Audi could be effectively protected with a modern aftermarket alarm such as the Sigma S30 CAT1 which is what I use and fitted by a someone who is seriously ****/obsessive/gimp you can confuse even the most knowledgeable thief but although the box is only £150 or so, a DEEP install could cost you £1k. You could also add glass break and vibration sensing on the many accessory circuits. I would also consider a tracking system, or like one instal I am doing at the moment an S30 with separate Excel 2 circuit transponder immobiliser (so four immobilisation circuits in two devices in different parts of the car with the boxes steel covered and riveted down) plus a tracker which you can call up and shut the car down (actually technically illegal) and a second tracker.
