We are hiring a modest car (Astra) for our 28 day driving tour of Britain in October. I have read articles about how best to avoid theft and/or breaking in a vehicle.
On some days, we will have our luggage in the boot (trunk we call it in the USA) and perhaps a small bag in the back seat, if it cannot fit in the boot.
We are largely visiting smaller towns such as Bath, Chipping Campden, Tenby, the Lake District, etc,. but are visiting Cardiff and York. What is the likelihood of someone breaking in our parked vehicle, which may be parked near our B&B or in a large garage?
In the USA, such crimes are not so common, if you park in a multi-deck garage or not in a bad area. However, I have read of some concerns here on this site.
