I really like this Corolla, which has only 98k miles and runs pretty much like new in my opinion. It stills get 36 mpg on highway and a good 33 mpg average. The exterior paint is still very good and the interior is actually spotless with no rip or tear. It is a good car with only one problem; the battery terminal corrodes and it won't start once a year. This is the battery problem and not the car fault and can be fixed with a jumper. Both battery and alternator are good according to AAP test. It is a tiny car and isn't exactly very safe if hit by another vehicle. There isn't a lot of power for the 1.6 liter engine. Is there a place I can buy roll cage for this vehicle? Also, what can I do to add some additional power to it? I wonder if it would be too expensive to just add a supercharge to the car without modifying items such as exhaust, intake, and others in order to keep the car low profile as well as keeping cost down. The reason for wanting power is that I travel on highway a lot and some roads have very short merging lane, which requires very good speed to safely enter. With this Corolla I have to time it just right as too much speed earlier insn't exactly a good thing. Most of the time there is no traffic so merging is no problem at all but it is nice to have the extra power because I tend to load a lot of things in the car when camping. Is there a later model engine that would fit into this Corolla the way Integra engine can fit into Civic? This car doesn't have ABS or airbag so I wonder if a bush/bumper guard is available for such vehicle. I know Crown Vic and few other cars have bumper guards so there must be bumper guards made for cars.
