2007 Nissan Maxima 3.5 SE 4dr Sedan (3.5L 6cyl CVT)
In an attempt to overcome it's severely lacking power, I put new 18" rims that are each 7 lbs lighter than stock, a new catback exhaust system, and a cold air intake from Stillen. I still could not get a 0-60 time that was under 8 seconds with about 20 tests. The car is unbelievably slow, mostly due to the horrible transmission and power band. The car creeps up to 20 mph before giving you anything, and then stalls out above 5,000 rpm at any speed. There's also very poor support in the aftermarket performance upgrades. Leave this sports sedan to your grandma and instead get a VW Passat, Infiniti G35, or Toyota Camry.
Interior is great. Exterior looks very nice. Love a lot of the little things, like the folding, tilting, heated mirrors, bluetooth, mpg calc.
It's hard to think of how they could have done worse in the performance department. It feels deceptively fast, but when you actually time it, you'll be shocked at how slow it truly is. The 0-60 claims by a lot of magazines are complete fabrications. There's no possible way they get under 7 secs.
