I have driven this this year & model car at least 450,000 miles. The car weighs 3770 pounds. This car is the first totally CAD auto built in the US. All were built in Linden, NJ. If any reader has problems with theirs call me at 610-564-8113. I promise I'll return call. Can diagnose over phone. Just bought 4th for $1000. 34K original miles. Have two definite MUSTS for all: 1) Next oil change use a chemical flush. Switch to total synthetic; 2) 90% of major problems are due to poorly designed catalytic converters. Exhaust flow restricted intentionally to increase torque. New LOW-RESTRICTION converter ASAP. Gas mileage goes from 8-10mpg to 14-17mphg. Over-heating? Change converter NOW! You may have 2,000 miles before you blow head gaskets. It has MAJOR collector potential. They all have the same problems. Don't ever want to drive anything else and am able to buy any type of car I want. I choose these. Bought 1st 8/11/77. 325,000 miles. It's as if they want to run forever.

Switching to synthetic oil in a car that old is asking for trouble. The seals aren't used to it, and if they aren't leaking already they soon will be after a few thousand miles of synthetic oil. Modern oil has improved by leaps and bounds since the 1970s, I used cheap oil from WalMart for 10 years in one of these, the car never burned a drop, and I still sold it with over 300,000 miles on it.

*ahem, http://theserviceadvisor.com/part/reman/buickbesttsagmc_403lb.html looks like a Buick 403, most likely just an Olds engine, but it does exist.
