If you knew anything about classic cars, you would know the best investment part is buying the car from the guy that spent the $ to build the car, or one of the owners after that. Once the car turns over a few times, the price stabilizes and then you hunt for the seller that needs a quick sale. Divorce, lost interest, needs capital for another car, building a home or business, etc. I know nothing about a Willys, I stick with what I know. 1st and 2nd generations Camaros and an occasional Nova or Chevelle. I made a trip to Atlanta last week to buy a nice 69 Camaro from a man that wanted to start a business and needed some cash. I left early morning and got home late that night and delivered the car to a buyer that netted me a few $k. You don't buy a car just to be buying, it's just like everything else, buy low, sell high.
P.S. That man overspent if he spent over 200k building that Willys. Cars in that price range are usually rare and highly desirable factory cars. Yenko's, Shelby's, Cuda's, Roadrunners. Resto-mods and highly customized cars are so taste specific, return on investment is hard to achieve.
Cars are an EXCELLENT investment if bought correctly.
