Vehicle Details
AI Listing Summary
This 1999 Mercedes SL320 Automatic, a two-owner vehicle with a recent power mechanism service and a full MOT, presents well with its original black leather interior and a like-new soft top. While it offers a comprehensive history with previous V5s and invoices, the central locking system needs repair, which may influence its sale value compared to its estimated range.
Condition
7
The vehicle is described as 'very original' with two owners since new and the soft top is 'as new'. The power mechanism was recently serviced, and it has a full year's MOT. However, the central locking is not currently working, indicating a minor issue that requires attention.
