NISSAN'S revamped 200SX is arguably the best performance-car bargain on the market today. Featuring a traditional front-engine/rear-wheel drive layout, the suave coupe packs a mean punch thanks to the potent 2.0-litre turbocharged powerplant lurking under its bonnet. A car that lacked visual sparkle previously is now a dead-set competitor for Subaru's Impreza WRX as the best bargan performance buy going around.
