Eyeballing the car, there are some issues that come up that bug the crap out of me.
It is definitely a Gen2 500SEC based on the WDB126044 (not 045) VIN. Started out as a 199 color car.
Engine has a Gen1 vacuum diaphragm, early (but revised) oil blowback system, no stampings on the RHD valve cover, the vacuum advance has a broken rubber connection (see pictured). How is displacement at 6.0 assumed? Based on paperwork? Most Gen1 DOHC motors were 5.0/5.4, a few 6.0's made their way in late Gen1/early Gen2 cars. Also just because it is aGen2 DOHC doesn't mean it is a 6.0, it can also be a 5.6. And whats up with the LHD intake air tube?
The wide body conversion looks good, but there's something about the lines of it that doesn't scream factory AMG. Maybe a later conversion? The car also has the "tucked"narrow rear bumper that was commonplace on non-AMG conversions. Would a real AMG wide body be sent off without an actual widened rear bumper?
Door cards are from a later 89-91 car. Does he have the AMG documentation to accommodate the car? I'd think if he bought it off an owner who owned it the last 30 years, that paperwork would be a definite given.
Also the rear trunk lip spoiler - I don't think I've seen a design like that ever. Nor does it look AMG.
Nice car. But I have some red flags personally.
