Where abouts Giles? I'm in Altrincham.
There's a girl (HOTTT!!!) with a 197 who I always wave to and after about six months she's now started to wave back. And there's an older lady (not bad to be fair to her) with a 200 (R200 BLU numberplate), she always waves back and her husband does too. There'a white Twingo 133 and he waves as well now, although he did look very confused the first time I let on to him!!!
Apart from those, it's very rare to see an RS around here.
