Up to last Saturday, my 10 year old Altima has been nothing but ultra reliable. It is a noisier car on the highway, especially compared to my wife's Accord, but otherwise a nice car to drive. It handles well, accelerates very well, with power to spare from its 4 cyl engine. Cruise control is a "must" to avoid speeding tickets! Until 3/14/2008, biggest maintenance expense has been for tires (Arizona roads eat them!), and minor maintenance. Saturday (3/15/8) morning, at 65 mph on the freeway the transmission failed. Car has 144,000 km (89,300 miles) on it. Failure occured within coasting distance of a dealership. Cost to repair almost $5,000. Grrrr!!
Excellent acceleration, lots of power, crusies at 75 mph at less than 3,000rpm in 5th. Handles the hills on I-17 north of Phoenix with no problems!
Road noise, especially on the highway above 50 mph is annoying.
