I just joined... I'm looking at buying an inline-4 2.5L Astro van, and I was wondering if it was underpowered. I could buy a Ford Aerostar, but, to be hojnest, I like the Chevy more. I'm just worried that the inline-4 won't have enough power. The better fuel economy would be nice, though. (I'm driveing a full-size Dodge van right now, and ther thing gets about 13 MPG -- not too bad, but when gas goes up it gets a bit painful).
