Cromas and Regatas are very thin on the ground these days, but in my opinion, the only cars at risk of complete, bonafide extinction are budget ones which fulfil only one purpose, that being cheap, disposable transport, from new. Say 20 years ago, some people would probably have assumed the Proton Lancer hybrids would vanish completely after a decade or so, but the careful owners who bought them in the masses turned that around, but what about the first Kia Mentors? Or the first Hyundai Sonatas? They sold virtually none anyway, and even now, are worth less than zero. No one has ever spotted a Lonsdale however! Also, didn't a Penza come up on eBay a few years back? Would be an apt car for me, my initials are SAO!
