How long did it take you to decide to sell your car

I have had around 100 cars in my life, not all of them classic cars as that number includes daily drivers also but, there are a few of the muscle cars I wished I would of kept. The last one I sold I have regretted since it drove away and, I won't do that again unless I have something to replace it with as it took years to get back into another car. I don't do the show thing I just drive them and hit the local cruise ins. Any day you can slide behind the wheel of an old car is a good day!!
