In the UK, it sits among grand-touring roadsters, above sports cars in refinement and price.
mycarcheck.com records 809 checks covering 374 distinct VINs, a useful sample; the average private-sale valuation was £33,300. Checked cars averaged 29,000 miles, around 5,000 miles yearly, and approximately 1.5 previous keepers. These figures describe looked-up vehicles, not a guaranteed price or condition for an individual buyer’s car or future value.
With its V6, automatic gearbox, folding hardtop and AMG Line styling, the SL400 suits couples seeking weekend drives and touring with relaxed comfort. Less suited to families or tight budgets, it costs more to run than mainstream coupes. Against the BMW 6 Series Convertible, it stands out for open-air appeal.
