Mercedes SLS AMG
The SLS suffered some of the most crippling depreciation ever witnessed in its sector when it was launched, leading many people to think it was a bad car. When it was in fact a fantastic car. Still is a fantastic car. Mercedes
just flooded the market with them and the trade began to get jumpy.
Unless you've spent time in one, it's actually quite difficult to describe how special the SLS is. I ran one for a several months and never tired of the gullwing doors or the fact that it never presented itself as a simple sports car. It was far more a muscle car that just happened to be very, very capable of going fast on road and track.
Values dipped to the low £100K mark a long time ago, but then sales slowed dramatically too, so the predicted fall to £60-£70K hasn't happened. If you offered me one or a new 991, I wouldn't even look at the Porsche.
Assuming you could actually buy one of the cheaper SLSs out there for, say £88K, I'm struggling to think of a sports car I'd rather have as everyday wheels. That's the modern Gullwing's real trick - it feels incredibly special all the time, and yet it is completely practical with a cabin that functions just as logically as every other Mercedes.
All you need to do is get the gearbox software updated to the latest spec and watch the fuel bills. And, if you have time, take it to the 'ring. I couldn't believe how good it was there straight out of the box on street tyres.
