Коротко и лаконично:

app.get('/cars/add/:name', (req, res) => {
const {
name,
} = req.params;

if (cars.indexOf(name) >= 0) {
res.send('Already exists');
} else {
cars.push(name);
res.send(${name} added);
}

});

const {
name,
} = req.params;

function filters(cars, name) {
for (let i = 0; i < cars.length; ++i) {
if (cars[i] === name) {

}
}
res.send(`ok ${name} add`);
return cars.push(name);
}
filters(cars, name);
});
