Thats the link...Tell them you want a complete system on a DELL D630 with DEVELOPER MODE ACTIVATED.This will have wis,tis,star finder,das- and Xentry, epc and give you the capacity to variant code, offline program, reflash, and change engineering configurations with such as show how many gallons left in tank on cluster,change lighting settings inside,change rear SAM features for tail lights, remove speed limiter  on any BENZ...I think it covers 1989-2015..I do many of those,but I make people sign a Waiver before doing so that I am not held responsible and it is the owners responsibility to make sure he has the tires,brakes,and all hardware to reach certain speeds, and if not it could damage the car or potentially cause bodily harm to driver. Also I have a clause in there that says by me doing so the driver is not getting the limiter removed to race or break any laws on Federal or State Roads..(sounds like a lot,but you must protect yourself in the event a young kid who just got a e55 amg for a low price decides he wants to crack 200 mph on the city streets, and at times I turn down some people). The newest benz I did was a 2013 GLK 350 I believe....  When doing variant coding with speedometers or any feature for the DME unit car must be running...and clear of codes  etc...Have fun, until next time Happy Wrenching!
