I have a 2002 Mercedes ML 500 and saw that my coolant bottle was cracked. I work down the street from here so i stopped by on my way to work and showed them what was going on. They were able to get the part the same day but when they replaced that they double checked everything to make sure i wasn't going to be leaking coolant anymore. They called and said my radiator was cracked as well. I went on my lunch break so i could see what they were talking about. They showed me where the crack was and also recommended to have the thermostat replaced. They explained i could cause more problems to my vehicle if i didn't replace the necessary parts. This being my only way of transportation i was a little hesitant but i agreed to have the work done and had my vehicle the very next morning :) I am also a very happy customer and will be returning if i have any other problems.
