240 SX? 240Z? I'm guessing you're asking about an SX because the Z car is rare these days. The SX can be very good in the hands of a skilled driver -- about 3 years ago there was a 240 in our region's STS class that was very, very hard to beat. They are prone to being tail happy, and that's what makes them a popular choice for the formula D crowd. But depending on the setup and the driver, they can hold their own on the twisties.
