Somehow I'd had him down as being more this:

Being born in the 1970s and a stones throw from Birmingham, Cadbury Purple would be ideal for me. I’ll save it for a beach buggy with it’s of huge metal flakes in te metallic!
 
I don’t usually post photos of cars I buy but this one might be a rare exception. It’s both a Mercedes and an unusual example at that, and so it might be of interest to some MBClubbers, so here it is.

Today I picked up a Kleemann SLK 55K S8. I know, I know it’s a little dull compared to a Mercedes-AMG ForFour Black Series AMG Sport Plus Night Edition Premium Plus 125 Navi facelift powered by Brabus.

It’s a one-owner low-mileage car which is in exceptional condition. I bought it from an ex AMG technician who has very very high standards, and anything not meeting his exacting standards was replaced.

It left the Mercedes factory with a naturally aspirated 5.4 litre M113 V8, but soon after it was supercharged by Kleemann and they also replaced the camshafts and full exhaust including headers and racing cats.

In period it was sometimes referred to as being the “Baby SLR” due to it’s F1 style “nose”, similar (but not quite) power output, and it’s deep chested bellow combined with supercharger whine.

Inside and outside it’s completely standard, with no hints of what can be found beneath the bonnet. It’s Obsidian Black with black and red two-tone nappa leather interior, and it’s all in fantastic condition.

The wheels are the optional five-spoke design rather than the more usual “Turbine” style. I probably prefer the turbines, but if I can find the right set then there might be a set of 19-inch AMG IV going on there.

Wow , I am truly envious ! What a beaut
 
I didn’t have chance to drive it over the weekend, but we’ve been out in it this evening for just the type of driving we plan to be doing in it, and we really enjoyed it.

We took it first to the gym and then back home via the chip shop (proper ballers), which involves lots of narrow country lanes and a few miles on a fast dual carriageway.

It seems quite grumpy and ill-mannered after a cold start, but it warms up relatively quickly, and becomes a little less grumpy once it’s fully up to temperature.

It’s far too noisy in urban driving when low speeds. lots of torque (770 Nm) and gentle application of the accelerator means that it shifts up very early even in Sport mode.

Once the road speed and engine speed both rise, the noise reduces and isn’t too obtrusive at all on NSL roads. even roof down and making brisk progress.

I wonder whether the excessive noise is drone - albeit at much lower speeds than I’d have expected (15-55 mph) - and could be tuned out with a few exhaust tweaks?

I don’t want to increase back pressure as it will reduce power but I need to reduce the drone. It’s intended for Mrs D to use to nip around in and the noise may put her off!
 
Mine has the x pipe and stage 1 map ( still nowhere near your power)when driven sedately you can't really here it but once you put your foot down its completely different very similar to the M156 c63 with burbles on over run 🙂
 
Just caught up with this thread. What an absolutely awesome machine, and in my opinion one of the best looking marques of MB sports cars made. That vehicle looks to me to be itching for a decent run out somewhere … 🤔😎😆
 
A Helmholtz resonator may be the answer here.
That’s the sort of thing I have in mind. Any suggestions on exhaust specialists capable of a top quality job?

Spyglass? 👀😁🍻
 
Our first proper modern-classic tuner car. For those interested in the performance, here are a few key statistics - it’s very very quick now but it was next level for a sports car back in 2006!

Most staggering is that back in 2006 the SLK 55K S8 was capable of accelerating to 100 km/h (62 mph) from a stand-still in just 3.7 seconds, and even 0-200 km/h (124 mph) comes up in just 12.3 seconds.

I’m fairly sure that with the right tyres and electronic speed limit lifted, the SLK 55K S8 would close the gap to the SLR’s top speed, possibly just braking the magic 200 mph barrier.

I can vouch for the mental performance. Back in 2005 or 2006 my first C43 was featured in Performance Car. PC brought a marque specialist along to have a look and he arrived in a Kleeman s/c SLK 55. Pretty sure it was the previous version but the same recipe.

When he left I asked him to give it the beans. Once it stopped spinning up the rears in 1st and then second it hurtled off into the distance.

Mental, even today.

Thank you for sharing. There can’t be many of them in the UK, I’ve certainly never knowingly seen one in the metal. That said my car looks no different to any other SLK 55 on the outside, and so had I seen it then I would have been none the wiser!

It’s very early days and so my thoughts may change over time, however I have done nothing more than tickle the accelerator in first and second gears so far, as I’m not convinced how well the transmission will deal with the torque.

When I have tickled it a touch more the revs build so quickly and the transmission changes so slowly that it doesn’t make for particularly smooth progress, better to be brisk in first and second and then apply a little more accelerator travel once in third.

Even in third gear, it still feels brutally fast for a car from that period. A more modern car with the same or similar power output is much faster in the real world, because gear shifts are much faster, and the handling and breaking performance is much better.

That adds up to make it feel like a bit of a hot rod, rather than a cut-price supercar. You can’t help but smile and hold on tight, even when driving at just three tenths! 😁

Look Mr D, you're obviously not happy with it, and not willing to admit you've made a mistake.
I'll pm you my details, you chuck it on a trailer, and we'll both pretend you still own it.
You get to save face, and I get a runaround.

:)

May i ask how/where you came across the slk?
