Thanks for posting - I just had to watch it again, even though I've seen it a couple of times before
In NZ many of those cars are a really common sight even today - the 6th-gen Toyota Celica probably most popular (let's say on a one-hour trip, you'll see five, and probably all red too), followed by the dated-looking BMW (three), and then the svelte Silvia and ugly Prelude (two of each). All of these will have been sold new and also imported from Japan at between three and seven years old, so it's like a steady supply years after production ceased.
The Mercedes would probably come next (one) and maybe the Volvo. Actually I think the Mercedes looks the most timeless of the bunch.
There are a few FIAT Coupes, then there are a very few GTVs, and I've seen one of those Peugeot 406 Coupes. These are all probably about as rare as each other and you might see one after making three one-hour trips.
I often wonder if their common-ness in the future might have affected the reviews these cars got at the time, if you know what I mean. I know Jeremy loved the Renault Vel Satis (and so did I) and it sold just four or five in a year in England. Therefore I think that would have been even more desirable, like buying a motor show concept car.
Conversely, would you buy a Celica if you knew that in 15 years' time, there will be a large number of them on the roads in battered condition and that they will all smell of hot grey velour and have faded pink doorhandles?
And would you want a BMW that looks so old now - I think it's actually aged worse than the Celica (at least the Celica looked sufficiently different to start with - that BMW looks like it's from 1992).
Meanwhile I've never seen a Calibra in NZ.
