The SLC isn’t long for this world so we’d take the published prices with a pinch of salt. Which is just as well because it’s an apparently expensive choice when you compare it against the equivalent Audi TT Roadster, though it’s a tad more affordable than a BMW Z4 and way cheaper than a Porsche 718 Boxster. Mercedes models tend to hold their values pretty well, meaning more palatable whole-life costs though – again – the SLC’s age will count against it on that score. With the diesel model now dropped the manual version of the four-cylinder SLC200 is the best for CO2 but any savings there will likely be wiped out come resale where most buyers will be after the more desirable (and appealing) automatic versions. No SLC is especially good on fuel or emissions by mainstream standards but, for the target audience and type of car, this is likely to be less of an issue.
