Thanks for your reply @Gaurav, the particular car will not go off-road, it is purely to be used in the city and maybe the odd sandlot if we come across in on our drives, not your typical off-roading at all.
I've stood next to the mechanic when he's shown me all the bits and bobs he's listed on the quotation so the work requirements seem legitimate. Although the car seems to drive without much of an issue so
I'm not sure which parts are definitely needed now versus what can be left as-is and replaced at failure. Another reason for posting here is to understand if the parts quotes make sense or are they using this as an opportunity to skim a bit off the parts price.
If it helps, I can always share videos of the observations, but I don't think I can post them here.
