This shows how much you know about cars.
Cadillacs are amongst the best engineered cars in the world. I think only Acura's rival their reliability and dependability. And as for performance they've outperformed Europe countless of times in recent years.
Cadillacs are definitely among the most reliable cars in the world, I am not sure I wouldn't go as far as to say they are among the best engineered, but that is subject to the individual interpretation of engineered (innovation, performance, reliability, consumption to output, design, space, technology, etc)
Cadillacs are definitely well made cars. I would push the shit out of a CTS-V
