I’ve just seen that a Mercedes-Benz SL73 AMG has sold for around €420,000. And honestly — this comes as no surprise. This car is a long-term investment masterpiece.
Yes, the R129 SL was produced for many years and in relatively large numbers, which is why standard versions don’t reach extreme prices. But this one is different. The SL73 AMG is a true unicorn.
Production numbers are extremely low — around 85 units worldwide. That alone puts it in a completely different league. Finding one today in impeccable, original condition is incredibly difficult.
If you have serious money and don’t know what to do with it, my advice is simple: find the best SL73 AMG you can, put it in a garage, and wait. Give it two years, and pulling €200,000 in profit is not unrealistic at all.
The engine is the key. A 7.3-liter naturally aspirated V12 — a power unit that simply won’t be built anymore. Mercedes is effectively done with engines like this, except for one notable exception: Pagani. And the fact that this engine architecture lives on in hypercars is not just trivia — it’s a value multiplier.
This is engineering from another era. Rare, brutal, and irreplaceable. Cars like the SL73 AMG don’t follow trends — they define them.
