Anything that can be said about a Sidekick also applies to a Tracker. They are the same truck (Hummm could add X90 to that. Same as a Tracker-Sidekick except for the body...). The Tracker-Sidekick can be found in 4dr hardtop as well as 2dr convertible and 2dr hardtop (up to about 1993). The convertible can be fitted with a removable fiberglass hardtop.
Having had both a Sami and a Tracker, if you are looking for a daily driver, the Tracker has a much more comfortable (smoother) ride. The Sami can be very jarring at times. Fuel economy is essentially the same for both, at least in stock form.
The 1.6 engine comes in two flavors, 8 valve ('89-'94(I think)) and 16 valve. I have never driven an 8V, so I can't say much about the difference, but the 16V seems to get better gas mileage and is rumored to have more power.
If you go soft top, the Tracker soft top (at least on my '96) doesn't seem to blow around and flap as much as the Sami top, and doesn't have velcro that blows loose every time a semi goes by. When it is cold and stiff, the Sami top really makes a lot of noise when the side panels flap against the frame. My Tracker is a '96, 1.6L, 16V, 5 spd, 2dr convertible with manual hubs. It is a great winter vehicle, especially with a removable hardtop, and very capable off-road even in stock form. The 2dr has a slight advantage over the 4dr off-road because the shorter wheelbase allows you to do sharper break-overs without scraping the rockers. The 4dr has the advantage on the street because you can lock it up, whereas the soft top just unzips if someone wants to get into it.
I would suggest looking for a 16V, 5spd, 2dr. with both soft and hard tops.
