Hello dear Mercedes S-&CL-community, I am about to buy a CL’s 500 (W415) and would have had only very specific questions, after I was able to pick and answer most of my own thanks to helpful contributions here. Today I had the opportunity to drive a well-preserved CL500 with 140tkm sample from year 2001. Has full equipment, from inside as well as from outside very well maintained, 2 previous owners, 100% original condition & complete AMG package. He has a relatively new e LPG system installed over which the seller (private) unfortunately does not have any papers etc. (Manufacturer: unfortunately nowhere to recognize) Now I have to consider that any defect to the gas system could be. Because the system looks relatively new and the seller wants to sell the vehicle now. Why invest about 2,000,-€ in the car and then sell it again after a few months??:S Should I rather leave my fingers off or nevertheless access the super offer??? Thanks already in advance!!!
