Cadillac's tech-forward mid-sizer—the car that pioneered front-drive luxury and later became the “Nurburgring” sport sedan. It's a brilliant driver's car, but the early Northstar V8s are a financial grenade.
The Seville was a mid-size luxury sedan. It went through four generations. 5th gen (1980-1985) was front-drive on the GM E-body platform with a 5.7L V8 diesel (105 hp) or 4.1L V8 (135 hp). 6th gen (1986-1991) had a 4.1L HT-4100 V8 (135 hp) or 4.5L V8 (155 hp). 7th gen (1992-1997) had a 4.6L Northstar V8 (295 hp) in the STS and a 4.9L V8 in the base. 8th gen (1998-2004) had a 4.6L Northstar V8 (275-300 hp). Transmissions: 4-speed auto (THM200-4R or 4T60E). The STS was the sporty version with a stiffer suspension and more power.
The early 5.7L diesel is a disaster—it's a gas engine converted to diesel, and it fails repeatedly. The HT-4100 is a time bomb. The 4.5L and 4.9L V8s are much better. The 7th and 8th gen Northstar engines have head bolt issues—the threads pull out of the aluminum block. The 1998-2004 models are better but still need meticulous care. The 4-speed auto is okay. The Seville is a fantastic driver's car, but the Northstar is a high-maintenance relationship.
