Вот тут проверить если значение уже есть в массиве то выдать сообщение об ошибке, иначе добавить в массив

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);
}
});
