Unfortunately because Toyota had to cut a few corners on this car to get it into the range of affordability they were looking for, there are a few minor drawbacks to the tercel. Looking past its noisy interior, cheap vinyl seat covering, a bad antenna/radio signal, the tercel is an awesome car. For me the only problems I've encountered are; one, bad rear-view rattling when my sub hits, and two, a "puffing" coming from the manifold (hmmm I wonder what that could be). Unfortunately, the only header to be seen being sold online for this car runs 500 dollars!
This car is cool because it's made by Toyota, therefore very easily modded and quite inexpensive, also I feel safe with driver and passenger airbags. Performace off the line is blah as you'd expect from this 93hp fuel-sipper. Still because it's a toyota there are a few really cheap performance mods for it including;
1. A cheap strut bar for this car can be bought for 20-30 dollars.
2. A cheap aftermarket high-performance intake for this car can be found everywhere online for less than 50 dollars.
3. Cheap blue-tined headlights and backup lights can be found for less than 20 dollars each.
4. If you have the cash you can even buy a NOS kit for this car for a little over 500 dollars.
5. In the back there are two holes in the metal underneath the carpeting near the brake lights, they did this so if you want you can drill or easily Dremel out two 6.5 inch holes in the carpeting and install 6.5 inch speakers. (they didn't install them for you to save money, but were cool and made it way easier to upgrade :)
