My Honda Del Sol Si... This was my first car and I loved it. I miss the sporty aesthetic and snappy cornering ability of this fun little car, but sadly as it got older, it started becoming more trouble than I was willing to keep up with. My goal was achieve 45mpg or higher while maintaining this car's sporty appearance. Sadly I never got around to some of the major body modifications that would have helped me achieve such a goal. I did manage a 42.7mpg tank at one point and averaged about 39mpg by the time I sold it. Good times.
