What's the best automatic Honda Civic 1996-98 model (ex. Dx.lx. Etc) as far as gas mileage and reliability?

I was interested in the 96-98 hx cvt civic yet there are many complaints of heavy vibrations when stalling.

Added (1). Also I can't drive manual and can't afford to take lessons

All trim levels of the Civic have the same mechanical abilities and the same reliability. The difference is the available features and options. The the EX is top of the line, where the DX is the base.

Ex power windows sunroof and vtec more resale value

The CVT has mediocre fuel economy when compared to the 83-91 HF and 92-95 vx models. Unless you have an Si performance, reliability, and fuel economy should be around the same. It really comes down to options.
