If I saw this car parked on the side of the road, I would pull over and offer to help. Maybe by loaning my emergency triangle until the tow truck arrives.
I have owned two of the W108 sedans. Seeing the car at ground level looks like the air suspension failed to my eye. Having lived in areas that often flood, I would be excited to know the car could be lifted above flood level. Please forgive my old fashioned sensibility. Men of my generation tucked their shirts in, and wore a belt on our trousers so our underwear would not be hanging out.
You have a beautiful car. It is a Classic. I have often thought if I bought a W109 or a W112 that I would prefer to install a system like the one you have instead of fighting the engineering designs of fifty-plus years ago. Your gear is probably more reliable and easier to maintain than the old stuff. I watch Fast and Loud on TV. This week they completed a trick hydraulic suspension. So, I get it. Enjoy your ride! I would give you a thumbs up when you cruise by.
Your friend's photography is fine art. You have a gift. I can see this work being published in magazines or showing prints at a high-end gallery. Cars come and go. You will have fantastic memories and photos. Thank you for sharing these with us. We do love pictures!
