That seems like the way of things but I think everyone is missing my point. ( not like
that's ever happened here before
) How much has that 190SL increased in value over the past couple of years? I bought my 190SL in June of 1993 and at the time I paid cash for it. Later that year in December I bought the Red Rocket and in that case I did have to finance it. The value of my 190SL, which is not running right now, is now more than what I paid for both cars while the value of something like a new Harley or a new car will go down every year until it bottoms out. So, regardless of what you paid for your 113, be it cash or finance, it will more than likely increase or at least stay the same during your payment period if you didn't pay cash. After all, didn't everyone say that they like the idea of the increasing values of MB vintage cars?
If you can afford it, buying the best car that you might have to finance makes a lot of sense. And, if you can lay down a good down payment on it, that could make it easier to consider. Assuming that you bought a good car, the value of that car will continue to increase or at least stay current with market trends. If you want to sell for some reason, you should have a top level example that could go to a high end auction or dealership with the potential to bring a good return.
One of the reasons the old car hobby is so strong right now is because of low interest rates. Someone buys a vintage car, drives it a little bit on nice days, owns it for a couple of years and then they flip it. An easy 10 - 20 K ( or more ) and it's a done deal. You couldn't make that kind of money with a GIC.
I know that many people like to start with a small purchase and work their way up. That makes a lot of sense for most and I'm right there with you. However, having a turn key car that you can drive today, take to car shows, win awards, and then see a nice return if you decide to sell is rather attractive. Spending the next 5 years covered in rust, sweat, and tears might also be attractive for some but in the end it all comes down to buying the right car at the right price.
I hope I've explained this in an understandable way.
