I wish there were photos of the ALCON brakes.
You can tell the ADS valve body failed by all the scrape marks on the under carriage. The mention of the front fenders getting repainted was probably due to the tires scrubbing the underside of the fenders and generating heat burns in the paint where they made contact.
I didn't know there were factory AMG catalytic converters. I just bought replacement converter pipes and wish I knew about these 3 months ago.
The car body is actually a little beat up.

Hahaha or this
🤣🤣🤣
I hope the current owners of the RENNtech put new bump stops on the front struts when they changed out the valve body. The bump stops keep the body up enough when the valve body fails so it doesn't contact the front fenders. You still have to drive VERY carefully back home if home is close. If not, then it has to be flat towed.
I did like the photos of the heim joint converted 5 link rear suspension. It looks like mine.
It should be a fun car for some lucky winner. I hope the new owners bring it back to it's former glory.

The one that went out the window was just a fiberglass shell, but the one built for driving was actually a pretty involved effort.

I snapped a couple of pictures of it at this years Pebble Beach Car Week.
Yeah someone paid a premium for it….

Any advice would be appreciated, as this is my first R129.
Thanks

Do a search on my name either here or on the other Benz website and you will find out what to do.
Aesthetically, the side wall of the tire should be about the same width as the upper tire gap to the body.
If you are looking to slam the car (it certainly can be done) to the ground, you may encounter some problems.
My own car has about the same gaps (but a little lower in the back).
The RENNtech cars have way more details that the AMG ones.
Brakes, suspension, interior, etc.
The RENNtech cars are much more unique.
This is what happens when you braille park a too low R129.
This is a good bump stop in that the 2 locating rebars aren't poking up an inch, but it still caught this new owner.
Bad habit.
The aluminum radiator.
The Alcon brakes.
The interior.
Heim joint 5 link rear.
Some of the cars box the underbody crossover braces.
Some of the cars have a closeout panel between the rear lower lip of the bumper cover and the belly pan.
Bunch of stuff.

If a AMG goes down the road and someone sees it, they say "Oh, there goes an AMG". If a RENNtech, Carlsson or Brabus goes down the road, folks will say, "What the heck was that!"
IMO, every R129 (specialty car or not) depends on the car. Low mileage and great condition regular R129s can rival specialty car auction prices.
In general, IMO, the specialty car SHOULD be worth more because there is more to them than the regular cars.
RENNtech cars are more unique than AMG, but their rarity may work against them at auction.
