It's still warm enough to car camp

We fancy another car camping session sometime soon so we are watching the weather forecast and it looks like it's going to be warm enough for us. Having said that we are tough northerners and don't feel the cold. It might be a bit cool at this time of year if you prefer warmer weather. We're going to have a look on the Park4night site to see if there is somewhere fairly close to home that tempts us.  Somewhere that we can see the stars tempts us so it will need to be a clear night. That might mean it's likely to be cold but we prefer the cold to the heat. Saltburn might be a good option but we have a couple of places in mind.
