The cruise control on my 1981 300 SD doesn't work. It apparently can't be repaired and estimates to replace it are quite high, ($1,200?). I asked about after market products but that also, according to our mechanic (who is proven trusted and competent over many years) is not possible. While our mechanic is good, they are not MB experts and I wonder how thoroughly they checked into my options. It just seems I could somehow get cruise control functioning restored without such a huge expense?! I like this car as economical, long lasting transportation, not because I'm an enthusiast ready to pay any amounts to have it in some kind of authentic, pristine condition. Any help or advice on a reasonable cruise control fix? Thanks! --Peter
