The nickname 'Pagoda' comes from the slightly concave roof on the hardtop version.
This lovely 1970 example has come up for sale on eBay as a classified ad, priced at £31,000. It's a 2.8 litre and is in pretty good condition, having spent most of it's life in California.
Interestingly it is a 3 seater. Take a look at the bottom photo and you'll see the rear seat is positioned sideways - even more whacky than the McLaren F1's seating layout.
The car has the ubiquitous 4-speed automatic and has done 102,000 miles and comes with both a hard and soft top.
The link to the original advert is here. Well worth considering if you're in the market for a pretty, rare, classic Merc.
