When I did my last service at Drive & Sh*ne @ Thalawathugoda. They charged 3100 for service cost alone (under body wash, engine bay wash, vacuum and interior cleaning) . Bill stayed exactly at 10000 without changing air filter. I used Toyota engine oil and a Union oil filter.
" polishing of dashboard, center console + Inside of windscreen" Big no for me too. Specially the inside of the windscreen, they make a mess wiping it with used towels, What you need is a fresh unused towel to clean the inside ant out, the mess is visible when driving at night.
