Is the Toyota Corolla a good car?

As a car, yes. While the humble Corolla might not be a Ferrari, they are solid, dependable transport that has served the world brilliantly for half a century. Cheap to buy and run, they are a bastion of reliability, they have good safety and equipment levels, and aren't bad on the eye, too. Classic Corollas are an excellent introduction to historic vehicles, while new vehicles are possibly the safest purchase in the new car market today.
