In this podcast, Jason Cammisa and Derek Tam-Scott ("Hyphen") cover everything you didn't realize you wanted to know about the R129-chassis Mercedes-Benz SL.
The R129 comes in many forms: 300SL, 300SL-24, 500SL, 600SL, and then the renamed SL320, SL500, and SL600. It had three different body styles and two interiors thanks to two facelifts, three different transmissions in the U.S. — a 4-speed automatic, a 5-speed automatic, and a 5-speed dogleg manual transmission.
And the 500SL/SL500 had 3 different engines: a CIS-E "K-Jetronic" tall-deck M119, a LH-Jetronic short-deck M119, both with 4 cams, 4 valves per cylinder, and VVT; and then a 2-cam, 3-valve, non-VVT M113.
So which is the one to get? Which variants drive the best? Which R129s suffer from the dreaded wiring-harness failure?
How much did Jason's 300SL 5-speed weigh?
These are important questions. But the Carmudgeons also talk about the R129's fascinating development history including — why the car that Bruno Sacco himself described as "perfect" was 10 years late. They discuss the R129's world-firsts, like the first-ever fully automatic roof mechanism (and its failure-prone 11 hydraulic cylinders), the first-ever popup rollover protection, the world's first seat-mounted seatbelts (with magnesium-frame seats); and the first time the world ever saw a convertible wind deflector.
The R129 was a technological tour de force, combined with a timelessly elegant and stunningly beautiful design and absolutely impeccable build quality, making it the high point of every generation of Mercedes SL — excepting of course the original W198 300SL Gullwing, which wasn't an SL at all.
Huh? Yeah, you're going to have to watch the episode to figure that one out.
