 I bought my 02' Altima from the original owner with 112k and it now has about 164k. Overall, it has been a good car with reliability that is comparable to Honda cars I've had. Apparently, there was a problem with the catalytic converter for the first couple of years of this version of the Altima but the first owner's mechanic had the foresight to swap it out and there has been no problems at all. The performance is great and so is the fuel mileage- I get close to 30 mpg on the freeway.For me, it has just been regular oil changes so I am pretty happy.
