Reason why that 2004 Buick LeSabre is getting attention is those have the GM 3800 V6 which arguably was once of the best engines GM ever made in terms of reliability, power, fuel economy. No other engine has been made with those 3 good attributes since the 3800 was discontinued in 2008.
The GM 3800 V6 dates back to 1960/1961 when it started out life as the Buick Fireball V6 which was used in the Special and Skylark around that time. Basically a Chevrolet small block with 2 less cylinders on it.
