Which Mercedes-Benz SL400 years should you avoid?

Not enough of the record to single a year out. Fewer than 4 Mercedes-Benz SL400 model years have at least 25 complaints and are old enough to judge, so any ranking would be noise. The table below has every year as filed.

How this is worked out: each year is compared with a typical year of the same model, which takes most of the difference in sales out of it, and its share of serious failures is compared with every other car of the same model year, because older cars were complained about differently. A year needs 25 complaints to be judged at all. Complaints are unverified owner reports. Full method →
