I have 3 model years as well, 92,93, and 94.
The 92 and 93 seem very similar to the amount of power. I can't really tell any difference. That is comparing the 1 - 92 and 2 - 93s I have.
Now for the 94. It is not fair to compare the 94 with the other cars because it has a 5 speed in it. It has the most power off of the line and feels like a true sports car because of the 5 speed. It is fun to run through the gears, and you can feel the power all the way through them.
As for a long trip, I would much rather drive the 92, or 93s because of better gas mileage, and ease to drive.
As for fun, out of all of the SVXen, SVXi, SVXs or SVXes, the 94 with the 5 speed is the one I would choose.
