Another recent example: I'm in Switzerland. I paid 550 CHF (630$) this summer for a "go-e Gemini" charger. I screwed it to the wall and ran a roughly 15m 3-phase 16A cable to the main fuse box (maybe around 50 CHF for cable and installation tubes), where an electrician connected it properly for 108 CHF (124$) and added an appropriate RCD for 116 CHF (133$). All in all, it cost me around 800-900 CHF (900-1000$). Without doing some of the installation work myself, the electrician would have cost me several hundred CHF more.
