Is The Mercedes Benz R129 SL A Future Classic? (Updated 2023)
23rd Jan 2023
Is the R129 SL a future classic? In short - yes! In fact, the R129 is a current classic. And it was a classic the day it was born in 1989. Perhaps the more pertinent question is, will the R129 SL prove itself to be a good investment?
Well, I’ve noticed that the SL is beginning to get more attention from investors, and not just your typical enthusiasts. Bruno Sacco's range of two door R129 SL roadsters are renowned for their fantastic build quality, timeless design and sophisticated craftsmanship. Lazy owners have sent most shaggy examples to the scrapyard, meaning the market is rich with well maintained examples.
The R129 SL is seen today as a highly desirable classic, but also an impressively practical and modern car. It commands an impressive average price in comparison to its successor, the R230 SL, not least due to its mechanical simplicity.
The Changing Value of the R129 in 2023
The value of the R129 has not declined for quite some time. Recent estimates suggest:
- V12 models have surged in value by over 140% in the last 5 years
- V8s are not too far behind, in excess of 70%
- Mid-spec six cylinder examples have seen a conservative 25-30% increase
With Generation X well and truly grown up - and sporting grown-up sized pockets - the usual cycle is in full swing. ‘Finally, I can get myself one of those SLs’.
History dictates that decent examples of this model will continue to appreciate, with the very best rising to many-times their initial value. Facelifted models are generally more sought after, as they come with a number of higher quality fixtures, fittings and parts.
"The [R129] SL is handsome and has plenty of smooth power from its V6, V8 or even V12 engine. Best of all, it’s half the price of its SL R107 predecessor yet much easier to live with. Rare AMG models and special editions will increase in value more than standard cars" - Jeremy Clarkson

Closing Thoughts
Of all models, the SL 500 (1997-1999) has by far the best build quality of the R129s. The Motronic engine is easy to diagnose and is near enough bomb proof. In my humble opinion, the SL 500 is the best R129 to buy and a sure bet for investors.
Thanks, and good luck! And get in touch with any questions as always. We love these cars and always enjoy talking with fellow enthusiasts. Carl
