The Appeal
The R129-generation SL320 is a luxury roadster produced in the 1990s as part of Mercedes-Benz’s iconic SL lineup. Known for its refined engineering, it features a smooth 3.2-litre V6 engine, delivering a balance of performance and comfort rather than outright sportiness. The R129 generation stood out for its advanced safety features for the time, including an automatic roll bar and adaptive suspension. With its timeless design, solid build quality and grand touring character, the SL320 remains a respected classic among enthusiasts.
Accompanied by a collection of recent maintenance invoices, this example is finished in Blue Black Metallic, with a black soft-top roof and a body-coloured hard-top cover, over a Helios leather-trimmed interior with burred walnut root trim, heated front seats, optional rear seats, and an updated Blaupunkt Madrid 200 BT stereo with USB, AUX and phone connectivity. Recently serviced in February 2026 at 84,099 miles, and with a valid MOT until July 2026, this robust convertible would make an enjoyable companion for weekend cruising, car show visits, and longer-distance road trips.
