Aria the Animation/Natural/OVA/Origination (past that is optional but still fine)
Initial D (First/Second/Third/Extra/Fourth/Fifth/Final Stages, anything else is optional/not recommended including MF Ghost)

Dub not recommended for aria, either is fine for initial d though tbh

pending reception to aria i'd easily bring up a lot of of other big iyashikei stuff but aria is the real benchmark there (yurucamp is flawed and horribly overrated though)

also supporting the existing to-watch list picks of Princess Tutu and Tatami Galaxy especially (and also seconding gunbuster etc. on comedies, i'd also second Nichijou/Daily Lives of High School Boys/Asobi Asobase, though i'd also add that Wasteful Days of High School Girls also fits in the same vein as an also decent side rec)
