1984 Cadillac DeVille 4-door Sedan review from Australia and New Zealand

Air conditioning compressor replaced three months after purchase.

Alternator replaced two years after purchase.

Throttle Position Sensor and Coolant Temperature Sensor have been replaced.

I hear lots of stories about the unreliability of the HT4100. I've done around 75,000 miles since I bought it in almost five years, and it is still smooth and trouble-free. Maybe this is because I change the oil every 3,000 miles and the coolant every year, and use the all-important coolant tablets in the radiator.

This is the most comfortable car I've ever owned, and its only drawback is the lack of power. I drive it daily, and thus it has to be reliable. As most of my driving is in peak-hour traffic, comfort is more important than raw power, so it suits the purpose.

Power leather seats, climate control, and all the usual Cadillac options make this car a real pleasure to drive. If/when the motor does eventually fail, I intend replacing the motor and keeping this car.

Considering the weight of the car, fuel economy is surprisingly good. The digital fuel injection is faultless and a credit to General Motors.
