2006 Mercedes-Benz CL-Class 2006 Mercedes Benz CL600 Twin Turbo V12 Tastefully Modified

Description

So, this has been my baby for a while now. We have done a lot of maintenance and improving. There are issues, but let's start with the good:
New Brake Vacuum Tank
New Battery
New Brakes
New Plugs and Coil Packs in 2020
Just did recent fluid changes on everything we could
New Wheels/Continental Tires 2019
Custom Exhaust
Custom Tune by PresserTech
There is Nitrous that has never been sprayed
There is a CO2 Intercooler Sprayer
Methanol Injection/Boost Pressure controlled
Paint was refreshed 2019
Removed Air/Hydraulic Suspension and installed full BC coil over suspension. I have sway bars/brackets that will come with the car, but we never installed as handling stayed very good after changing suspension
Suspension Module from Strut Masters (no warning light on computer, but lights for buttons stay illuminated)
K&N Intake Filters
CryO2 Water Sprayer for intercooler
Innovate Wideband/Boost Controller
Burberry Rear Deck
B Pillars were just re-done in new Alcantara (old ones were stained from grease from previous owner)
Now, issues...The A/C stopped working recently, which doesn't bother me as I just leave the windows down. The head liner needs to be fastened better, it moves a bit in the higher speeds with windows down. Boost sensor for Innovate gauge has gone out, says I'm boosting 43.8 PSI with car at idle. I will try and address this, but now it's funky. I have the new contact plate and connector harness for transmission. Not having any issues, but it’s at that mileage for regular maintenance.
It's a fun car that I have driven all over the place, including from Pennsylvania and back. Now, it does have a rebuilt title, this was due to catastrophic suspension failure that did some damage to the fender up front (from previous owner). They bought the car back, put new suspension components, control arms, fender, and a ton of other work and got it on the road. Of course, after a while, I had issues with the suspension and upgraded to the BC system with Strut Masters.
I'm trying to make some room in the garage and free up some cash for new projects we've got (two race cars...).
