"presumably the stats are reflected in insurance premiums."

Good point. Just tried a quote for a softtop convertible. The premiums are on par with an equivalent hatchback

" I was thinking about buying a convertible, I certainly wouldn't be put off due to security concerns"

Thank you. comparing premiums with hardtop seems to confirm what you said. No significant change in insurance quote

Never leave one parked in a street with the top down. It will get used as a litter bin, and be spat in, yes, disgusting and a sign of the times possibly but a friend had that happen outside a supermarket, it was keyed as well. Perhaps just that particular area, normal town, but definitely take precautions and park carefully.

If youve never had one before I would hire one for a few weeks to make sure you get on with having a soft top.

I have had them a number of times as hire cars abroad. I wouldnt buy one.

In the sun in a soft top I tend to get burnt.

With the top down I end up with lots of dry dust in my hair, which over a few weeks makes it a few shades lighter.

If the weather is bad and the top is up visibility is much worse than a hardtop, noise is worse.

So although there are fun for a holiday, I dont see the point for day to day use at home.

I compared quotes for Peugeot 108 with and without the fabric opening sunroof, the cars with sunroofs had a highrer premium ...

That is as likely to be related to the profile of the insureds as it is to the car's security. Clearly there is a possibility of vandalistic slashing, but from a theft point of view it is probably easier to smash a window than start cutting through a soft top.
