I met a guy the other day who was also driving an LS. He was an older businessman, who was a manager at the local Lincoln/Mercury dealership. We talked for a while about cars, and I asked him what the most common LS repair that he makes at the dealership. He told me that hands down, it was coils. I told him how I recently went to his dealership and had my coils replaced, at the tune of $1700. He decided to give me a deal on any future part or service I might need. Now, he is going to sell me coils for $30 each. So, if anyone needs NEW OEM coils just PM me.
