87 GN with T-Tops For Sale


Jan 7, 2004
I have a 1987 GN that I have owned and babied for about 10 years. The car now has a blown head gasket on the passenger side. I can fix this head gasket or have it fixed; either way I'm moving on. The car has 89,000 original miles showing on the odometer, however the freshly built motor has about 5000 miles on it. This car is set up with quality parts because I have never cut corners or spared expense. It has a 109 block that was built by G&G in Houston TX. The car has a couple of rust bubbles on lower passenger door. I wrecked the car when I first got it, front cap only had to be replaced along with a complete new paint job for which I paid the difference. Fiberglass bumper fillers put in at this time on both front and rear. The car has a clean and clear title. It does have small chips and a few small scratches from normal wear and tear that would take a keen eye to notice. Other than that, I've described the condition of the car exterior the best that I can. Please keep in mind that I am very particular about the condition of my car and it was always kept in a garage. The inside of the car is in great shape other than two small wear spots on the passenger seat and on passenger floor carpet under the floor mat. The only other flaw in the car is that the gas gauge works intermittently. I just replaced the gas tank with a new gas tank and fuel sending unit, but the issue is in the speedo cluster. If you have questions concerning cause of head gasket issue read this link below because the car has a safe tune on it right now and this is my best guess at the moment and I didn't use washers. http://www.turbobuick.com/forums/th...uter-studs-under-valve-cover-too-long.366491/

I am asking $14,000 as is with the blown head gasket, but if I have repairs done, the car will be in the $15,000 price range. I am open to any and all reasonable offers and you can contact me on my cell # (337)515-3808. Please leave me a message/voice-mail if I do not answer and I will call you back. I am a shift worker, days/nights so I keep strange hours. I can also be reached by email me at dyer1170@att.com. I am looking to invest in a new project with funds gained from the sale of this car. I do not need to sell it, just feel it's time to move on, so please submit only reasonable offers.




This car is back up an running thanks to jpwalt! This car was dialed in perfectly but had non aspirated head gaskets on it that were put on by G&G. The car is now back on its feet and done right with Cometics head gaskets. Fuel injectors were sent off tested and verified to be in proper working order.
