Very little has gone wrong.
Faulty radio antenna base, replaced under warranty.
Broken compartment lid in the central consol, replaced under warranty.
My only gripe is that the brakes wear out quickly (discs front and rear), and have to be replaced quite often.
I have owned or driven dozens of cars over the past 40 years, all of them European (mostly British & French with a couple of Fiats thrown in). Mostly were quite comfortable, but very few of them could be noted for their reliability, and I was quite used to visiting the garage between services to have various faults repaired.
A friend persuaded me to purchase the Toyota Corolla Gli saloon (he was on his third). What a revelation! quiet, comfortable, roomy, reasonable road holding, and above all reliable.
This Corolla was designed in France and built in Turkey, so I suppose you could call it European.
Great build quality, no rattles, well finished.
Excellent road holding, good acceleration, and reasonable petrol consumption.
Good spec. it came with all the usual electrics, climate control, and a good quality single CD player.
In all, this is the best small family car I have ever owned.
