1987 Buick Grand National "GNX"

Basic information and History

An incredibly nice and genuine Grand National that has been upgraded with original GNX parts. Imported from the USA back in 2005 and the seller who has owned it since 2018 has put a lot of time and money into upgrading and going through the entire powertrain. The Grand National (and GNX) is a very rare model on this side of the Atlantic where the 86-87 model is the most recognized and sought after model from Buick and was their fastest accelerating car ever when it arrived. Even today, it offers performance that stands up well!
