1991 Mercedes-Benz 300SL-24

Some cars come and go, but the Mercedes-Benz SL has had staying power. Ever since the mid 1950s, this name has been going strong in the lineup, transforming from the original Gullwing coupe to a smaller hardtop two-seater, to the boulevard cruiser of the 1970s and 1980s and into the present day as a refined but capable luxury roadster. One of my favorite SLs was the R129 from the 1990s. It was no easy task taking over from the iconic R107 SL which had an impressive 18 year production run. This car was literally the face of Mercedes throughout the oil crises, recessions and the boom times of the 1980s, yet stayed fashionable all along. However, the new for 1990 300SL brought back an option to US buyers, albeit for a short time, that was lacking throughout the R107 production run: the manual gearbox.

Yes, you could order your 300SL from a US showroom with a 5-speed manual, making the most of a 3.0 liter inline-6 engine that was tasked with moving around 4,000 lbs. of car around. If you’re used to a V8 in your SL, performance is a bit underwhelming in this model, but given that only a few hundred R129s were sold in the US with a manual gearbox, the novelty factor is certainly there. This 300SL-24 for sale in Arizona is one of the nicest 5-speed manual R129s I’ve come across in my time at GCFSB, tempting for someone who absolutely must row their own.

Right off the bat, the asking price had me doing a double take. At this level, some of the best, late model V8 and V12 R129s can be had. Six-cylinder R129s, no matter how nice, are not at the $30,000 level just yet, even if equipped with a rare manual gearbox. There’s no denying this is one of the nicer 5-speed manual R129s, but from the comparisons we’ve seen, we’re looking at a car that’s worth around the $15,000 mark, maybe pushing $20,000 if the right buyer came along. This is another one of those cars that, if given the garage space, I would love to have because an R107 or R129 SL with a 5-speed manual has been high on the wish list for some time. Sure, some people would argue the automatic was a better pairing for such a car, but for me, only something with a third pedal will ever do.

  1. Price seemed a bit high, quite a bit, but where are you going to find another one? Then again, the ad has been removed so maybe it sold.

  2. It’s already gone, you’re just rubbing it in…

  3. No worries on the car being sold already…the manual is notchy with a long throw and is really not fun to drive. I test drove one a few years ago and decided to pass on it. Not *every* car is better with a manual transmission…most, but not all!

  4. Looks like it’s not sold…not that surprised at that price… http://phoenix.craigslist.org/evl/cto/5423227556.html

  5. ALL US-bound R129s with the 6cylinder engine were 24 valves. The 12V engine was ROW and rarely sold anyway.
    As said before, the manual transmission was not really fun.

  6. My understanding is that the gearbox and shifter mechanism on these are basically the same as those on the 190E 2.3-16 (dogleg pattern, etc…). As such, some upgrades are available. Usually the factory bushings are worn by now–Delrin replacements really tighten things up. There are also one or two individuals out there who will modify the shifter arms (lengthening them slightly) to shorten the throws a tad.
