We've been crushing chuckaways and unisnured chavmobiles for almost 2 years up here. We work with an insurance company's sponsorship on this.

(oooh.. they'lll think we make a few bob outa this.. .. we think it helps keep our bobbies on beat

)
We target the cars which are more than likely to be this genre. Unfortunately, this was an old vehicle and possibly attracted attention because of this.
In ideal world (and I think we did manage to drop a right clanger here once .. we tightened up - apologised and made appropriate ex gratia compo and thus maintained a fair PR job

) .. but .. once the document had been produced at the station and then verified by way of a few other checks - including contact with the insurers.. car is made ready for release and fee waived.
99% of time.. bona fide cop though and the reason why we crush?
We are back to the same vicious circle if we send back to auction of the £60 unroadworthy defective and the chav driver from hell.
In fairness to GMP .. they have a very serious problem keeping tracks of all the pool throwaways on their patch. One of the blackest spots in UK for this kind of unlicenced chav-mobile caper.
Not excusing them.. stay of execution should have been placed on that car - but easy to see how mistakes will happen given high volume of chavmobiles getting seized.. and these are only tip of the proverbial iceberg.
As for the "authority to destroy" this car.. obviously this will feature in any investigation and no doubt appropriate action taken if found to be "not in order"
I do feel sorry for the gentleman in this case and sincerely hope my colleagues down in Manchester/Bolton can resolve this with him with the best outcome.
