The Pagoda roof SL is definitely one of my all time favourites, alongside the W124. There was a beautiful pale blue 230SL car in my local dealer yesterday, on German plates for some reason.
As for summer prep, I've had all the fluids and filters changed, 4 new tyres, and next week I'm changing the Poly-Vee belt tensioner (the beariungs have dried out and it is shrieking) and I'm having the air con disinfected.
