Negative.

For '01 you 4x2 XE, 4x4 XE, 4x2 SE, and 4x4 SE. You had had the 4x2 XE I-4, which had an inline four cylinder for the engine instead of the standard six you see in about 98% of Xterra's.

What price are we looking at? A '01 with 39K miles should be in excellent shape. Does it have the extended warranty (100K miles)? Did you run a Carfax on it? Was it offroaded heavily?

Like Prolific said, your stock unit should play CD-R's. It won't play mp3 CD's however.

The manual limit to tow I believe is 3500 pounds but that's mostly a safeguard thrown into the manual by Nissan because most people screw up towing heavier loads with a manual and Nissan protected their ass by stating that so they don't have to deal with the idiots. I've never heard of anybody of burning out their the drivetrain by towing heavier, but take what you will. Cyclemut could probably explain better.
