I have a 2000 GS-R Sedan. The only thing I do religiously is change the oil every 3000 miles. There's been nary a problem with this car and the longevity of its design is a testament to its outstanding quality. This car is a blast to drive. I love rowing the gears and the engine loves being revved to the limit (of course, as I do this so often, I rarely get more than 24MPG, but hwy can exceed 30MPG for long treks). Large gauges, sweet engines, easy control use. Honda built a great car!
