Buyer Advice

The Mercedes-Benz SL-Class, particularly the V12 SL 600 models from this era, represents a compelling blend of luxury, performance, and classic GT styling. With a limited market of only 24 total listings, patience is key. Focus on vehicles with comprehensive service history, as V12 maintenance can be costly. The average price point is around $24,700, but condition and mileage significantly influence value. Given the moderate days on market, expect negotiation opportunities, especially on listings that have been active for longer periods. Thorough pre-purchase inspections are highly recommended to uncover any potential maintenance needs.
