Junkyards or Salvage yards: Check local junkyards or salvage yards for used motors. You might be able to find motors in working condition at a fraction of the dealership's price.
Online Marketplaces: Websites like Craigslist or Facebook Marketplace often have used car parts listed for sale. You might find motors for your power seats on these platforms.
Online Auto Parts Stores: Search online auto parts stores for aftermarket motors compatible with your vehicle. Some stores offer budget-friendly options.
DIY Repair: If you're handy with car repairs, you can try repairing the existing motors instead of buying new ones. Sometimes, the issue is a faulty switch or connection, and fixing it can be less expensive.
Local Auto Repair Shops: Some auto repair shops may have access to used parts or may be able to repair the motors at a lower cost compared to the dealership.
Consider contacting local car enthusiast forums or groups specific to Mercedes-Benz models. Members of these groups may have recommendations or leads for affordable motor options.
Remember, when buying used parts, inspect them carefully and ensure they are in good working condition before purchasing and installing them.
