My first cousin who is a close friend has an 02 5 speed w/ LSD with every bolt on (headers, cam gear, flywheel, SRT intake) and I really enjoy the car. For 10k or less I would call it a unique very tunable car for a good deal. Anything more and i'd probably just hold on to my money....
Pro's
-great chassis, predictable and quick for what it is
-smooth inline 6
-tunable, very, but it's not as easy to make big power as some say
-Fun to drive, he has shocks/springs and it'll hold its own on a fun track day
-nice interior bits (gauges, knobs, speakers, Nav on some)
Con's
-Cheap quality you usually get with small japanese sporty cars
-has had lots of maintenance. I don't recall but they dumped $1400 in it right away when it only had 60k, then 2k trying to get it to stop sucking down oil. It drinks a quart like ever 1000 miles. Basically it was obvious that the only way it would stop drinking oil would be with a new motor (this is when it only had 68k).
-light almost dead shifter

If I were given 10k to mess around with, I would consider it, but call me biased there is no way in hell i'd buy one when I could get my hands on an M3/4 which is in stock form, is a much better performance car and also very easy to make a solid 300-650 whp out of.
