BOXTER vs Z4 vs G35 WOW FOR ME IT'S A CLOSE CALL BUT MOST DEFENITLY HANDLING WOULD BE THE BOXTER. POWER TO RATIO WOULD BE THE Z4 AND THE G35 IS JUST QUICK AND GOOD STEERING IN ALL COMPARISON I WOULD SAY THE BOXTER. HAVING TO OWN ALL 3 CARS IS JUST FABULOUS AND JUST TO THROW IT OUT THIER I ALSO HAVE A NISSAN ARMADA 4X4 AND THIS BEAST WOULD TOW AND CARRY PEOPLE WITH EASE.
