For the marginal difference in gas milage, I dont think it's worth the lack of power (20hp). If you've already bought a car with the 8v SPI motor in it there's not a lot of cost-effective solutions for that though.. just live with it until you can step into a better car.
Another difference I noticed between the trim levels was that the LX was offered with a standard tape deck and optional CD player most years, where the SE had the CD player standard. Stuff like that, also aluminum wheels vs. steelies with hubcaps, etc.
An SE with all upgrades and options was comparible to a ZTS in most respects I think, minus leather. I think you could get leather in the ZTS anyway.. I never really paid attention to sedan options since I'm all about the hatchback.
