We should all remember though, that although great to look back on with rose tinted specs, and still nice to look at today, with most modern cars no more distinctive than the average fridge - most of these old cars would be complete shite to drive these days.
And some listed in posts above would have been shite to drive even when they were new, imo.
I was thinking the same, as almost all posters have listed older cars, but even though I've had 3.0S Capri, RS2000 Custom, 3.5 Rover Vitesse TP etc., I wouldn't want any of them back other than to sell on. And oh boy, do I wish I'd kept them to sell on, well the Fords at least.
I'd genuinely struggle to name ten cars as my ideal garage collection.
Audi RS6 Avant (practical load lugger that gets along a bit)
Audi A6 Avant 3.0 BiTdi (for speed with some economy)
M Sport Kombi Transit Van
M Sport Transit with day van mods
Bmw 535d/335d M Sport Touring (regardless of what people think of Bmw, the user interface is very good, (less clunky than some other premium brands), as is the ZF-8 transmission). I've had a fair few Bmw 3 Series/4 Series Coupes over the years but they are no longer practical for us so I'm done with them and I hate convertibles of any brand (even though we did have a Bmw F33 for a while).
And from here on I'm stuck. I'm not really into supercars, as in owning one (RS6 excepting).
I know electric is the future, and they are very fast off the lights, but I have no interest in any of them yet.
There are no good or bad lists as everyone has their own fond memories/dream car list, so we'll all differ in our opinions.
