Came across this earlier tonight, a kind gent from Pistonheads has scanned in a bunch of road tests from British car magazines from the 80's. The scans of relevance to us:
M635CSi test from 1989 - http://www.flickr.com/photos/7869726@N0 ... 137467538/
635CSi test from 1988 - http://www.flickr.com/photos/7869726@N0 ... 135889797/
If you sign into Flickr, you can get the scans at full resolution so the articles are easily read.
