We are in negotiations with the dealer. They said I was right about the leak and they'll have to remove the engine to fix it, if I still want the car, and they would want a higher price for it. Trying to work out a fair post-repair price for both parties. I figure if it's done there and guaranteed for life I'll give em a little bump for that. No future worries about that issue would give some peace of mind. I told them if they can juggle numbers and get the payment where I want it for 48 months, I'd go for it.
