W116 AMG body dress up parts don't do much for me, value wise.
The exhaust system may help, but I wonder if that is an AMG part.
I note no mods to the engine / drivetrain or suspension.
Suspension wise no modification would be needed. That can be driver modified, simply by adjusting the ride reference height.
This is a Zircon Blue 6.9 that was previously registered with the number plate '450 609'.
Last time it was advertised for sale it was for $17,000 (don't have a date) and it had 275,740km.
There was no mention of AMG stuff then.
Ho hum car is not amg speced at all just new amg badges fitted. Looks like rust under boot amg badge. Has ford xr6 tail pipe tips fitted with duel exhaust. No amg front spoiler. And 6.9 badges on front gaurds with new amg badges under neath. Car looks to ok with regards door trims seats not so good nor carpets. Might be ok if half the price. Geoff
