My pleasure :grin
I'd say there are a few members, who have W168 as a second / third runaround car, someone I know from another (UK) forum, just about to buy an A190 as his third Merc.
Even though I drive a C169 A200 nowadays, I have had more than a couple of W168s over the years, both here in the UK, and in The Bahamas before that (Jap import), and done a number of mods - will be happy to share.
BTW, if you're in UK, and if your A160 is missing a folded up seat support, you're welcome to mine.
Page 169 of the manual shows where it is hidden (some people own their cars for years without ever finding it), and page 170 - how to use it.
