It's the old to each their own in my opinion. I bought my car to drive and have fun with it. I don't know what the value will be down the road. I have kept all stock parts so I do have the ability to return to stock if desired but it would be slightly molested ha.
That car has 17,800 miles so they did about 450 miles per year. The internet says the MSRP in 1968 was $2,881 - $3,539. Since I'm a numbers guy if I took $3,250 as a base escalated by a 5% annual return (probably may not be attainable each year from 1968 - 2019 but whatever) you would have $24,000 today. I took a base of insurance starting at $100 ( I have no idea what it was in 1968) and increased it by 3% annually. Insurance would've cost you $7,500. So him owning the car cost in $31,500 not including any additional repairs and maintenance. There are other factors but for argument sake I am keeping it simple.
Yes getting $72,000 would've been great if you wanted to just enjoy seeing the car sit in your garage and appreciate in value. For me drive it, have fun with it and don't worry about 40yrs from now.
$72,000 less $31,500 is $40,500 of gain. I'm sure he loved cleaning, washing, waxing and having it in his garage so he could say he had an awesome Camaro. For me to have the enjoyment of driving a car for $1,000/year ($40,500 gain/ 40yrs) is worth more money than someone ever could give me 40yrs from now! But then again I am a simple man.
