Wow! a 6 hour round trip, in the UK most of us are still in lockdown, maybe buying a CS can be seen as an essential journey? 
There do seem to be a few more cars up for sale, mostly trade type cars, in that they appear to have higher average mileage or a basic specification.
I prefer to buy and sell privately, that way you can see if the seller has a clue, or even buy a car known to this forum, as I did.
The used car sector is still very much ongoing throughout lockdown and there are rules around collecting cars etc. No test drives, which is understandable but C&C or delivery from dealers. The rules around private sellers are not so clear. But a car is essential for most people for work. I have to commute daily for work and have worked throughout each lockdown. I also have the option to collect the car on trade plates as we are still collecting cars from auction sites as they are still operating online for collection.
I’m seeing the huge price mark up when they have the Recaros in them. But some private sellers are expecting similar money for a standard car. It’s better dealing with a one owner private seller for sure, just a waiting game now.
Must have for me is 3DR, Manual, DCC, Dynaudio (Buckets a bonus

)
