95 acheiva rocks

i have a 95 acheiva s , v/6 for several months now and it runs and drives great.the acceleration is outstanding!! it has about 60,000 miles on it now. i changed serp belt and gas filter and coolant .it is one of the hardest riding cars i ever had. it slams along the road like a tank. i noticed on consumer reviews they mention these cars are like that from the get go.it averages 25 mph,city/hwy. actual hwy mpg is excellent = 33 mpg at 70 mph w/ a/c on. i also have 98 chevy lumina with same engine ,but no competition.
