This is my 3rd Buick I've owned. Always liked the comfortable ride and good gas mileage (33 mpg on highway), and ample room. However at 82,000 miles the car developed an antifreeze leak. Took to local Buick delearship and they had to replace lower intake gaskets (8 hr job) and water pump. Total cost over $1100. After searching the web, found other GM car owners with same problems, and most common culprit was the Dexcool antifreeze now used by GM and plastic gaskets that get eaten away by the Dexcool. No wonder Toyota and Honda are selling so many cars. It's called quality and reliability!
