My first Isuzu was one of the early first generation Impulse's. I absolutely loved it. Joe_Black is right, the thing was bulletproof. I put almost 175,000 on mine with almost no repairs other than maintence. I even went snorkling in my Impulse (quite unintentionally) and the thing still ran great. The stock Fujitsu Ten (who also makes Eclipse) sound system with in dash EQ was pretty darn good. Also, the movable instrument clusters on both sides of the main gauges was pretty unique.

The only problem I remember was the one wiper arm. It looked really cool... but in heavy down-pours, it couldn't keep up, and became distracting.

I have driven nothing but Isuzu products since. Two Troopers before my daily driver VX. Rob
