Mercedes-Benz SLK55 AMG: Buying guide and review (2005-2010)

Mercedes-Benz SLK55 AMG: Buying guide and review (2005-2010) Classic and Performance Car

The best AMG Mercs are ever so slightly bonkers. For the first SLK55 they squeezed a 5.4-litre V8 into the R171-gen SLK bodyshell and created something wild and really rather wonderful. Naturally aspirated, the engine developed 355bhp and a walloping 376lb ft of torque – enough to rocket the diminutive SLK from 0 to 60mph in well under five seconds, all accompanied by a thunderous muscle-car soundtrack. 
OK, so the stability program – which couldn’t be fully disabled – could be a little frustrating, but such was the 55’s appetite for rear tyres most owners would forgive it that. And with the folding metal hard-top providing GT-like refinement when you weren’t in the mood, here was a car with a broad range of talents. It was also the official safety car for the 2004 F1 season. Credibility was assured.

Which one to buy? 

AMG’s hot-rod went on sale in the UK in 2005 and the last ones left showrooms in 2010. There was a facelift in 2008 that sharpened the F1-inspired snout and brought a number of worthwhile improvements – including a 10 per cent quicker gearshift for the 7G-tronic auto (there was no manual option on the 55). There was also a Black Series version with slightly more power, slightly less weight and lashings of carbonfibre, but these are incredibly rare and hence expensive.
The great thing about the ‘regular’ SLK55 AMG is that it offers fine value, with prices from as low as £15k. But a word of caution. These may be affordable, but that doesn’t mean they’re going to be cheap to run. The AMG components are often fearsomely expensive to replace – particularly the brakes. (And while you’re thinking costs, note the jump in road tax for post-April 2006 cars, from £280 to £490.) Be on your guard and check the history fastidiously to avoid big bills lurking round the corner. If in doubt, get it inspected: a couple of hundred spent now could save thousands.

Common problems

• The 113-series V8 is ‘bulletproof’, and generally regarded as trouble-free. You hardly ever hear of any problems with them, but it’s always good to remove the airbox and check for gasket oil leaks
• A recent set of spark plugs gets a big tick. There are 16 of them (specialists charge £5 a plug, Merc dealerships £10) and it’s a two-hour job to change them, so even an independent will charge the best part of £200 for full replacement.
• Make sure the gearbox has had its fluid changed at 40,000 miles – essential to prolong its life and avoid a major bill. If the shifts are smooth it’s probably OK – their speed and trigger-points depend on how the car has been driven. 
• The gearshift in the earliest cars was rather dull-witted, but there were a number of software upgrades to improve its responsiveness, so try to confirm these were done.
• The earliest cars had a particularly impressive brake set-up with six-piston calipers. After 18 months these became a (rarely taken) option and a four-pot set-up became standard. Either is more than up to the job, but the discs are formidably expensive – budget around £1000 just for a pair of fronts, even from an independent. 
• If the handling feels out of sorts, the front suspension arms may need replacing – fortunately not an expensive job. Potentially very costly, though, is any damage to the alloys, so check for anything more than light kerbing, including the inside of the rims for pothole damage.
• Standard interiors are a little plasticky but build quality is good. Check the roof mechanism works just as it should – they’re generally reliable but any repairs will be pricey.
• The most common fault is with the heated seats; if the elements in the base and backrest need replacing it’s a £1700 job.

Summary and prices

You should expect to pay £10k-plus for an average-miles 2005 car with a full service history. £15-20k buys you a really nice 2005/2006 example with desirable extras. The Airscarf neck-heating warm-air system is highly prized, and the Comand infotainment system too (though its satnav isn’t great). The Harman Kardon hi-fi is nice to have, as is the upgraded Designo interior. Post 2008 facelift cars start at around £20k, rising to around £27k for an end-of-the-line 2010 car.
