Your Grande wasn't the very base model though. I'm referring to the Actives with wheeltrims and no colour coded mirrors or door handles. I saw a few of those advertised, and possibly with lower miles too, but I ignored those in favour of Dynamic models and the Eleganza I bought, because they had the side and curtain bags.
Had a quick read and it was only the cheap actives that didn't have curtains but then they didn't have side impact airbags either, they just had a driver and passenger bag.
Oh, I know that, I was merely surprised that such mainstream (and not exactly cheap either!) cars weren't fitted with them, that was all.
The UP! The mii and the citigo all rank in the cheapest uk cars as does the twingo so they are very cheap. And for the 5th time curtain airbags do not automatically mean a safer car, which bring us neatly to your next point
I would still feel safe in a Panda, from what I understand, most of the difference in the ratings is because the Panda has less driver aids as standard.
As I've already posted the UP!/mii/citigo all score much better than the panda for adult occupant (7% safer in the the Vag car) and child occupant safety (17% safer in the vag car) so ignoring your brand loyalty, it's an average 12% safer to crash an UP! Than a panda, which is quite. A bit!
It is 3% worse to be run over by the vag car but if you're the driver you're probably more concerned about your own safety than the idiot who wonders into the road in front of you.
Equipment wise the panda does terribly it got half the marks of the UP! But actual safety wises as an occupant of either vehicle the UP!/mii/citigo is quite a bit safer by NCAP standards.
Not sure why you keep mentioning the metro a car that's not been built for about 18 years, things have come a hell of a long way since then, it's not even remotely compatible to any modern uk car.
In a 50mph crash I'd rather be in a rally car than the best ncap scoring car and the rally car won't have any airbags.
Airbags are not the be all and end all when it comes to safety. The idea of not buying a car just because it doesn't have an airbag that covers the back windows in an accident is just silly. My golf has huge rams that burst out of the parcel shelf in the event of a roll over with the roof down but that doesn't mean that all the cars that don't have this technology are any less safe.
