While Chicane may present his points in what some people think is an antagonistic manner, he makes some valid points.
If you are buying these cars because you think the price may go up on them tomorrow, next month, next year, or in the next decade, I would advise you to rethink your motivation for purchasing.
I remember when the collector car market crashed in the early 1990's and people couldn't get near what they paid for something in the late 1980's.
I have seen the vintage guitar market crash in the last couple of years and I happen to believe that the collector car market is over the peak and on the way down, just like many other "collectibles" are correcting right now.
The rise in collector car prices was fueled by the same money that caused a bubble in real estate. Excessive speculation using other people's money with a perceived future return that would be greater down the road.
Will CSL owners see excessive price gains over the next decade? Possibly... but there really is no guarantee that they will. When Chicane states that "past performance is no guarantee of future results" he is absolutely correct. We saw it in the stock market, we saw it in the housing market, etc. If someone can explain why we won't see similar corrections in the collectibles market, I would be more than willing to listen.
How are collector cars different than tulips (

Keep in mind that one thing that has contributed to the rise in prices with these vehicles is their age. As a car reaches beyond 25 years in age it generally starts to appreciate in value faster. This is because the target buyers for what, at 25 years, makes a car a "classic" are the buyers who, at 40-50 years old, can now afford the car they wanted in junior high and high school.
We have seen this with every decade since cars were first produced...
If you want to buy a cheap car now so you can sell it in 10 years for a lot more than you paid, I would tell you to keep away from the E9's and consider something like an M6 or a 635 CSi. Those cars will be cheaper to get into now and will probably return what you put into them much more easily down the road. But it's still not the best place to invest your money because it's not an extremely liquid asset and it takes up a lot of space.
Anyhow, if you think CSL's will become unaffordable soon, on a never ending trajectory of appreciation, then I think you should review pricing on cars from the 20's, 30's and 40's first. These three decades have passed peak pricing and now have a lot more sellers than buyers. Are their exceptions? Certainly! A hand built Duesenberg is worth more than a Ford or Chevrolet from the same period, but CSL's were produced in sufficient quantity that one shouldn't consider them "rare" by any means because they aren't.
As far as what people have been casually or seriously offered for their car or what their car is "worth" today according to a price guide or what a knowledgeable friend tells them or a "gut feeling" they may have on their car's "value", experience has shown me that the only time a cash value can be attached to a car is when it is finally sold to someone else.
Much like the housing market, the only time actual value is realized is when money changes hands. Anything else is simply guesswork and speculation. All of the above can aid in determining an asking price, but what you ask and what you get may be VERY different when you finally have the cash in hand.
Buy a CS or a CSL because you like the car, not because you think you should "buy now or be priced out forever" or because you want to consider it part of your "portfolio". Buy the best example you can find at a price that makes you and the seller content with the deal. Just do your research BEFORE you buy, not after!
As far as whether the CSL should be "worth more" and is "undervalued", unless you have enough cash to manipulate the market, the entire discussion is somewhat academic. None of us can force people to suddenly desire these cars enough to inflate their prices, can we? It's a pointless discussion to even have. "Should" they be worth more? Give me one good solid reason WHY they "should" be worth more? Simply because more people find another car more desirable to possess? That's not a valid reason. Remember, at the end of the day, it's just a way of getting from point A to point B, nothing more. Of course, I wish EVERYTHING I bought appreciated in value 2000% the minute I bought it, but that's not how life works, is it?
It's just a possession that will one day be on the scrap heap whether through rust, accident, nuclear war or because gas is $50.00 a gallon.
