I don't know you but I know Keith but we are all brothers here! I have been around Buicks over 25+ years and one thing I can tell you for sure; once you get the Turbo Buick in you system, no matter how hard you try you will not be able to get rid of it. I have friends that sold their Buicks 10, 15, 20 years ago now wants to get back into another Turbo Buick. It's like Heroine, once it's in your system, it will so hard to get rid of it.
Keep the car brother; there are many good Turbo Buick guys out here to help you out with anything you need as long as you have the passion. If you do sell it I can guarantee the fact that you will be itching to get another one and regret your decision. Trust me I've seen it far too many times!
