Anyhow, someone backed into me today, and my van might be a total loss.

I will probably be in the market for a new van, but it will be another gas model, for a few different reasons. I was thinking of trying the 2.4 L gas engine. Figured It might be a bit lighter on fuel.
Anyone have any experience with the 4 cylinder gas engine. What are parts availability? I know the v6 is the engine that's in the montero, among other north american vehicles, so parts are easy. How is the power? I'm not a race car driver, but the diesel is really slow on the freeway, how does the 4 cyl gas compare?
Any info would be great.
