I don't daily drive the W123 since I got the S124 last year. Until that, the W123 went everywhere I did, from my 20 mi round trip work commute to 2600 mile roadtrips. Same with my previous W123. Before that I daily drove my Vanagon with a manual and no AC, so the W123 was a major upgrade.

These days I work mostly from home so all three cars get far fewer miles now.
