SL/R129: Service a and b on 1992 500sl
Keep in mind that these services packages were designed under MB FSS (Flexible Service System) which was introduced after your model year, I believe, and they are only available through the Dealer.
Your money may be better spent taking the car for a pre-purchase inspection by a qualified local MB independent shop. As long as they have the Star Diagnostic System, your possible purchase can be checked out using the Diagnostic System. This plus other site inspections will run about $150+/-, and will be the best prepurchase investment you can make. Anything discovered by a qualified tech' inspection can be used to either disqualify the car for purchase, or provide you with a list of needed repairs that you can use in negotiating the purchase price. Good Luck
