The AMG wagons are genuinely scarce US-market cars and their exact counts are debated: the E63 wagon is cited as about 152 US cars, and the E55 wagon variously as 193 (129 of them 2005) or 215 per corrected archive figures. A knowledgeable owner claims to have owned 7 of the 152 E63 wagons, underscoring how small the community is.
