if you have the money get a S14 since they are generally in better condition. also they have a slightly longer wheelbase and have a inch wider track then the S13. all this leads to better high speed stablity if you like to play on the highway. also the S14 is less prone to understeer compared to the S13. however the S13 usually weights 200 lbs less. so its cheaper to make it faster in the straight line, and it should stop better, and feel more nimble casue of the size and weight difference.
