So after browising around I came across this auction llisting for what is being represented as Iron Mike Tyson's 1990 500 SL AMG. While it may check out as actually having been his car at some point in time, it appears to somehow only have the AMG appearance package without having any of the engine uprgrades or AMG branded odometer. I know plenty of modern model year 2000+ mb's that will have the AMG appearance package (bumpers, side skirts etc..) but someone will have to enlighten me if this was a factory option at the time. Looks like someone did a fairly decent job if this was added after the fact as fitment looks decent and it appears to also have an AMG stamped exhaust...

Ask Mike or AMG.

Great intro to talk to the Champ.

There is no initial indication that this car has a 6.0-liter AMG M119 engine.
The only way to find out is to check the bore and stroke of it.

Its an AMG body kit on a regular car and a muffler.

The real value is if its really the Champ's former car.

I say get in touch and see if a dialog ensues.
