1985 Cadillac Fleetwood Brougham 4.1 from North America
The car sat for almost 7 years and was driven less than 3000 miles in 7 years. I bought it from a friend for 1000.00, and started it and drove away. The only thing I find wrong with the motor is it hesitates on occasion.
I drove it 500 miles to the coast for Thanksgiving and it only used 110.00 in fuel. The gas gauge is broken, but computer says it got 16.5 to the gallon. I like it; a comfortable ride and a perfect interior.
Would you buy another car from this manufacturer? Yes

I hope you know what you have gotten yourself into purchasing an HT4100 powered 80's Cadillac - especially a heavy rear wheel drive one. That engine is the worst engine ever put in a Cadillac. Even worse than the 350 diesel.
The HT4100 is known for the following major failures: camshaft, timing chain, main rod bearing, intake manifold gasket, head gasket, and oil pump. The only advice I can give you is change the oil every 3000 miles, flush the antifreeze and use the very important cooling system sealant annually. The sealant is available at any GM dealer. Never let it overheat and keep your fingers crossed.
This engine was not even intended to be put in a heavy RWD Fleetwood Brougham. They did it to meet CAFE standards for 1982. Cadillac geared this car real short because the engine was so low on power and torque. It's geared at 3.42:1 so the engine is always revving high up the RPM range; therefore the engine is constantly being overworked and tears itself apart over a relatively short period of time - similar to a 60s Volkswagen. The average life expectancy of a HT4100 is 80,000-100,000 miles. Good luck.
