Here's the deal, most if not all bike thiefs want to 1) pedal away, 2) push away, 3) motor away, they rarely ever have a pickup or the like waiting and ready, cause let's face it, it's the desperation easy grab a convience store robber with no thoughts previous, he saw it, he wanted it, it was easy, so why not.
If you live in an "area" I first suggest considering, is the cost of living there worth the money you make when everything such as worry/turmoil about theft on a daily basis is constantly there?If so, then quick releases (granted this part is where CG frame builds DO NOT shine) are better than expensive heavy locks cables, most stores will let you keep your wheels/saddle behind a counter, even taking off just the front wheel will stop 98% of thiefs, they will not carry it away.Remove both wheels at night, and they will think someone already hit it and it won't worth the sack of whatever they need at the moment.
