Bought my '97 Infiniti I30 in 2000 with 30K miles on it. It is now 4/2012 and I'm at 363,000. In mid-atlantic (USA) weather. It has only needed regular maintenance. The largest repair bill I've ever had was just under $2K (ball joints-control arms). But that was well past the 250,000 mile mark. And they do eventually have to be replaced :-) It still runs great. And the leather seats are still very comfy, show very little wear and are quite supportive. It has been incredibly solid. Love this car! I think the fact that it has a timing chain instead of a belt really helped it's longevity. The V6 and transmission in this car are incredible!
-great bose sound system -very comfy leather seats -power seats for both driver and passenger seat, nice luxury touch -very good fuel economy, I get 24-25 with soley city driving because i"m a kid -although I dont drive like one, but i did one time, the only time my parents paid for a tank of gas, i got 19-20 mpg by beating on the car -it takes premium fuel, i dont put it in and still get stellar gas mileage, i dont recommend it though, you will get better gas mileage if you do put premium and is the engine is much happier, you can hear her hum more smoothly, better performance, ^^btw all of this info is in owners manual(when referring to the fuel type needed)
This is my second I30, last one was running fine at 140k. I now have 155k on my 97 I30, it runs as if it was new. Car is not as peppy as most people say, takes about 9-10 seconds to get to 60 mph. Handling is disappointingly spongey, stiffer suspension would be great. Since owning the car I have replaced the radiator, brakes, egr valve, knock sensor, the spark plugs and front struts. Engine and tranny still feel like new! If you are looking for a comfortable decent looking commuter car, than look no further!
I bought my 97 I30 in 2000 with 38k miles on it. Now in 2007 I have 125K miles on it. Durring that time I have had absolutely no problems. The engine is just as quiet as the first day I drove it. No interior rattles or squeaks. I would like to buy a newer vehicle but I can't see trading in such a reliable automobile for another. Maybe the engine will finally give out at 200k so I can get a new car.
