Trading in financed car?

I have a 2016 Hyundai with 35k miles. I still owe $14,500 on the car. Is it possible to trade the car in for instance, a $9,000 used Honda, without owing money? My goal is to eliminate monthly car payments.

Can the Nissan outperform this Honda?

The car is a 1998 Nissan Altima gxe, which I saw for sale. The car I'm comparing it to is my 2003 Honda Element Automatic. Both are equipped 4 speed automatics. Both of them have 130,000 miles. However the biggest difference between these two is the curb weight and the aerodynamic drag. The manufacturer specs claims 150 how, 154 ft lbs torque on the Altima. The Honda produces 160 how, 161 ft lbs torque.

Clearly on paper, the Honda produces more power but my question is how would the Honda do against the Nissan on the freeway? In terms of acceleration, handling and overall performance? Can it keep up with this older car? Is the Honda Element the slowest car on the road or it's just on par with every other normal 4 cyclinder economy cars?

Will replacing the control arm and sway bar bushings increase trucks handling?

My truck is a 2003 Honda Element 4 speed automatic. Whenever I get on the Freeway where the speed limit is 65 mph, most people rocket down the highway doing AT LEAST 75 MPH and traveling as fast as 90 mph! It's on a parkway though that extends for as long as 20 miles. The problem with my truck is when I approach speeds of 65 mph and higher, the steering starts to vibrate and I have to keep the steering straight with a bit of force. Wind restistance has not been an issue despite my truck being non aero dynamic. My question is how significant are the control arm and sway link bar bushings to my car? Will it improve my cars handling in Corners and highway cruising speeds?

Also one more question. Will lowering my truck by a good .5-1"
How can I achieve my car reach it's top speed a little quicker? I'm asking this because one time when I was on the interstate highway, particularly on the overpass which which extended as long as 2.5 miles, there were literatally no cars around me, the wind conditions were perfect(no wind restistance, not to cold or hot) so I decided to get on the gas to see what truck can do. As I went up the speedometer from 65 mph, it had no issues accelerating up to 95 mph but once i passed 95 mph it creeped up to 100 mph slowly. Now my foot was on the FLOOR, HOWEVER the engine was not redlining as I was only doing 4100 rpms. The tachometer reads up to 6500 rpms. Surprisingly, the truck was able to hit 100 mph with my foot on the ground(not redlined).
