Check for pre-owned Mercedes

[Cbenz]

Dears,

i am planning to purchase a pre-owned 1 year old e200 (w213) from a dealer. The car is still under the standard 3 years C&C warranty.I recognise that warranty only cover costs of parts but not costs of labor.

Before purchase, Can you advise if I should bring it to C&C for their used car check service (think it cost 250 SGD and they have 33 points check)?

I am not sure how different or better is that compared to STA or Viacom and whether is it really worth the process.

i am also not sure if there are trusted workshops doing such pre-purchase checks (Guess subjected to dealer comfort level).

thanks much for your advice in advance

if cnc does provide used car check and is under warranty should be quite ok i presume.
