You can really learn how far a car has come by visiting where it's been. Last week we drove the Porsche 991.2 Carrera 4S, and today, we go back to the older, naturally aspirated Carrera 4 GTS,. This one has been modified by TAG Motorsports of Vista, CA with an AWE intake, Exhaust, lowering springs and wheels, so it's not a stock-for-stock comparison, but it will do the trick.
