I think parts cost me about 250 dollars. I got all seals, belts, hoses, waterpump, etc... Also, I bought some new snap on tools that cost me 400 dollars on ebay. I have a invoice of work performed on my wife's 97es300 and the total was 2200 dollars from the dealer. The previous owner gave me the receipts which showed crank and cam seals, timing belt, and valve cover gaskets. That's all that was included for that 2200 dollars!!!!!
