The History of 1987 Buick Grand Nation
Factor CF5 Atsro-roof car
VIN# 1G4GJ1171HP416683
Stillman & Hoag Buick of Englewood, ew Jersey ordered this vehicle in November 1986. At that time the dealership was managed by Walter R. Stillman, ho recently passed away in October 2015. Mr. Stillman was the son of automotive hall of fame member Walter W. Stillman. Walter W. Stillman took over the dealership in 1937 from his father, ho founded the company in 1908. After assuming the business operations Walter W. was the first to go door to door inviting families to test-drive vehicles. He often displayed new Buicks at the local railway station for train passengers to see. Hence he is considered one of the great automotive sales innovators. Walter W. instilled a strong work ethic, hich was often displayed by his son Walter R. Stillman who took over the duties at the dealership in the 1970s. It is said the Walter R. was aware of and part of almost every sale made during the 1970s and 80s at the dealership especially the “special” vehicles such as the Grand National. Mr. Stillman operated the dealership until 1999 when he sold the dealership to General Motors.
Our vehicle was invoiced in November 1986 and was sold some time in 1987 to a New Jersey owner. From there the vehicle was on a journey that took it to four states that we know of.
1987 (purchased in Englewood, J) until 1997 the vehicle was in New Jersey.
1998 until the early 2000s the vehicle was in Florida where it spent some time at Chang’s Car Care Inc.
2001 until 2012 the vehicle returned to New Jersey, hich included Toms River, utherford and Cliffwood, ew Jersey. The owner at this time was Harry, ho purchased the vehicle while it was in New Jersey. He did very little to the vehicle and said that the modification done to the car where installed when he purchased it. The modifications included an alarm and radio system and a larger intercooler and turbo.
2012 the vehicle was sold to Robert in Pennsylvania who lived just blocks from our home but we never met Michael or saw the car. Michael purchased the car with hopes of restoring it but decided against considering the work involved.
2012 the vehicle was sold to a young musician named Michael and the vehicle was driven to Hampstead/Windsor Mill Maryland. Michael only had his driver’s license for 2 years and this was one of his first vehicles
2014 Christmas day we purchased the
vehicle from Michael on ebay and trailered it back to Pennsylvania.
