On the first day, a kid in his earky teens shouted "nice car, mate!" and walked off. I smiled.
I have seen a few people walk past our drive, and stop and stare, then carry on again, checking behind them as they walked off. A car even stopped across the drive once, while everyone in it admired the car, the drove off again. I didn't like that too much.
I have also seen faces pressed up against the windows
in Sainsbury's car park.
In a courtesy SE diesel, as I was negotiating a a junction on a high street, I got a two-thumbs-up from a guy shouting "niiiiiiiiiice caaaar!".
