I've had a '96 and a '99 Discovery Series I. The '96 had problems, but the '99 has been nearly perfect. Since 1999 was the last year of the Series I, I suspect that Land Rover managed to iron out the bugs of the previous models. Then, they brought out the '99 Series II, and it all fell apart again. Other than routine maintenance (brake pads), this has been a rock- solid vehicle. With gasoline prices rising, I decided to drop down to 87 octane fuel instead of 92-93 octane premium, and actually get better gas mileage with the same performance! The emissions are probably worse, but how much worse? When I can save 20 to 30 cents a gallon, I am happy to do it. Buy a used '99 Series I.
