I purchased my second 1999 Park Ave after trading in my first 99 for a 2004 Grand Prix. While the Grand Prix is sporty, it doesn't hold a candle to the size, ride, mpg and trouble free driving I have experienced with the Park Avenue. I routinely get over 30 mpg on the highway and over 20 mpg in the city, that is better than my 4 cylinder pick up truck! I purchase my current Buick with 57,000 miles on it and now have over 112,000 and have only had to perform routine maintenance on the vehicle. It is a comfortable, reliable ride that I never get tired of. I also have a 2007 Lucerne, but as nice as it is, I prefer my Park Ave and will replace it with another when the time comes.
