Welcome to the forum, and compliments on the rare OZ rims.
H & R springs would be a good thing, they still leave a fairly comfortable ride.I was under it today, it could be the springs, the ride height arm hasn't been touched. But I never actually looked, I will be under tomorrow again and I will check. If they have been replaced H and R springs are the ones to go with or should I be looking to swap something else in? I am comfortable with the height as it sits, any lower and I'll wipe the front lip off any higher and I might feel like truck.
Feeling the edge along the wheel wells will tell whether the fenders have been rolled (another good thing).Back story of the car is missing some details but I can fill you in on what I know, car has 270+Km on it, but the car was only ever summer driven. Very well taken car of and washed almost daily by the elderly man that owned it. No maintenance records but compressions sold under body is in great shape and I opened it up and the timing chain is almost new. Sold it to some kid that thought it was cool, I was selling my car and he asked if I would be interested in trading, I was once told "One thing everyone should do is own a Mercedes at least once" So I looked at realizing what it was, the shape it was in decided I had to have it, I have like the w126's for a long time but being in Canada cars of this age normally have rusted out fenders. This one doesn't have any.
And I am still attached to the rims, I think the make it look aggressive for the long door it is, but if I ever find something else that works I'll remember that.
The plaque on the cross member shows what kind of factory engine the car came with.I'll grab a photo of the headers tomorrow, but I know the car has had work done to it (Slotted and Drilled rotors on the front and back, the front and rear euro bumpers, permanent air filter AMG Muffler, could be the whole exhaust system I didn't really check)
