1993 Mercedes-Benz SL700 RENNtech


Back in 1993, if you hopped down to the local Mercedes-Benz dealer and asked for a 600SL, they’d gladly give to you — in exchange of giving them almost $130,000. If you somehow were dissatisfied with the car in terms of performance, you called up Mercedes super-tuner RENNtech and told them to do their thing with it — in exchange of another $60,000. Now doing some quick math here, we are at a grand total of around $190,000. Keep in mind we are still talking in terms of 1993 money. To put that in perspective, that’s over $316,000 in 2016 dollars. And you thought a drug addiction was expensive! So what did this insane amount of money buy you?

Tuner Tuesday: 1989 Mercedes-Benz 190E 2.6 – REVISIT


The ex-Vlad 1989 Mercedes-Benz 190E 2.6 with plenty of modifications that we wrote up nearly two years ago has resurfaced for sale again. Offered by the buyer from last time around after covering only 3,000 miles, the asking price is close to what the seller paid. However, a few things of note – several items are no longer working, the bodywork is cracked and – most notably – the BBS RS wheels are an optional extra for $3,000. Has the W201 market appreciated 50% on a questionable example like this in a year and a half?

Tuner Tuesday: 2009 Maybach 57S RENNtech

Sometimes, enough just isn’t enough. The Maybach perhaps personifies that statement better than any other single car produced by Mercedes-Benz. The W221 S-Class certainly is no slouch, even with the smallest motor fitted. But, someone at Mercedes-Benz said it wasn’t enough, so they fit it with a 5.5 liter V12 twin-turbo motor producing 500 horsepower. But then, that wasn’t enough, so they made an AMG version with a M275 6.0 liter twin-turbo V12 which produced 604 horsepower and a mind-bending 738 lb-ft of torque. Insane, right? Well, then someone at Mercedes-Benz said that wasn’t enough, either, and they fit those W221 internals into the even less pedestrian Maybach 57S. In the past few years, Mercedes-Benz has been known for their nutty excess, but even this was really over the top. So over the top, in fact, that very few people bought them – in 2010, despite a budding luxury car market world-wide, Maybach only sold a reported 157 examples of their version of ultimate luxury worldwide, and in 2012 closed down all-together. But some people did buy them, and for them, of course, the standard Maybach wasn’t enough. So off to RENNtech this particular example went for their “package 1” which involves a reflashed computer and new intercooler pump. Sound mild? The result is 670 horsepower and 840 lb-ft of torque:

Tuner Tuesday: 1993 Mercedes-Benz 500SL RENNtech 6.0 “SLammer”

Since their launch, the R129 Mercedes-Benz SLs have held my attention. Perhaps it’s because I was heading towards driving age when I first got to sit in a then-new 500SL, but regardless of the motivation I really wanted one. My father used to take me to the local Mercedes-Benz dealership in his W113, so even though I was a child who grew up in the 1980s I was never particularly partial to the R107 – and I’m still not. Early Euro-spec cars look nice to me, but for the most part they look a bit too soft and large. So the R129 was a revelation – it looked substantially more sporty and was thanks to a new 5.0 V8 good for 320 horsepower mated to a 5-speed automatic transmission. But for some well-heeled enthusiasts, the $100,000 price tag (in 1993!) wasn’t enough. AMG was in a state of flux in the early 1990s, but there was a new kid in town that was grabbing some serious headlines – RENNtech:

Tuner Tuesday: 2006 Mercedes-Benz McLaren SLR Renntech R1

The supercar market has always been a bit perplexing to me; get past the glam and the glitz of these showstopping performance machines, and they generally are seldom used toys that depreciate quickly. You don’t hear about someone having saved money their entire life and walking down to a McLaren dealership to buy a P1, for example. That means once they’re no longer grabbing headlines, the well-heeled owners move on to the newest, biggest and best thing to impress their friends. Back up a decade and there was a massive showdown in 2003 between the Porsche Carrera GT and the Mercedes-Benz McLaren. With nearly equal power output, price and performance, one would have presumed that in today’s market they’d share equal value. Both were and are very special cars, and similar production numbers made it to the United States. But today a good Carrera GT will set you back half a million dollars, while you can grab the McLaren for less than $200,000 today:
