I have had my 92 300 SE for 11 mos. and it has 51,000 miles on it and I now have 65,ooo miles. I have had several electrical repairs made and the head gasket replaced. Even though I purchased the extended warranty good to 100,000 just over two more years of ownership, I feel I need to make some decisions on how long I keep this car. My question is, are the parts that are being replaced any better than the originals? Has Mercedes recognized the much discussed "electrical Gremlins" and what have they done with their R&D? I would appreciate any advice and discussion!
