Not for the Faint at HEART!!!! This vehicle has had some Renntech Programming and is absolutely one of the fastest vehicles I have ever driven. Stock it is 493HP but I can tell you that I just sold a stock 2005 S600 that had nothing on the power this vehicle has. 0-100 in the blink off an EYE. There are RennTech badges on the fenders and trunk. I just spent $2400 at Worldwide Mercedes in Indianapolis having all new engine mounts and Transmission mounts replaced because of the insane power it has. The ULTIMATE SLEEPER!!!! Originally MSRP of over 135K. Every option possible including Adaptive cruise. EXTREMELY RARE!!!! I Did have an A service done at the same time. Feel free to call us at 317-477-1600 with any questions you have.
