Hello, At the moment im just about to advertise my Merc ML270, hoping to sell it buy the next weekend, and my plan is to buy a 330 CI Sport. Im not the most talented at working on cars but i know enough(i hope). I have read the buyers guide and theres some very usefull info there, but what else should i look for, i have about £4-5k to spend and im looking at around a 2002-3.
