No, I would never buy an SE-R of this generation (02-06). Theyre possibly the most self destructive cars sold in america right now. About 40% of the 02s have literally eaten their own catalytic converters, and had to have their engines replaced under warranty. If any body here is thinking about buying one, go read here first.
Mine has the 1.8 liter base model engine, but after the stuff Ive done to it its about as fast as a stock SE-R. It has intake, header, exhaust, and intake manifold spacers, and it makes about 130-140 horsepower at the wheels. And because of the sticky tires and suspension work done to it (coilovers, rear sway bar, nismo front control arms, strut tower brace, etc) , its quite a bit faster than a stock SE-R in this kind of stuff:
