I’ve att need two Shelsley Walsh breakfast meets, one with the ISF, one with the RC-F CE. Nobody stopped to look at the ISF.
The RC-F CE, totally different. At one point there were 8 people crowded round the car.
Bottom line, if you want to be discreet, get an IS-F, if you want some attention, get a RCF standard edition and finally, if you want to stop traffic - go for the RCF CE.
