I think it’s wise to remember that when it comes to looking at new cars – YouTube is probably your best friend. There are numerous reviews for all new models – a lot of reviews inform you of what’s standard & what’s optional – and remember; reviews of each model are always added every single day – so keep checking back. I have lost count of how many car reviews I have watched during lock-down! Many of the reviews are superb and very detailed. One particular sites’ reviews are an hour long for each car!
Also worth remembering that if you type the make & model you’re interested in into Google & then ‘PDF’ – you should get the manufacturer’s downloadable brochure for that car with a complete list of what is standard & what’s optional for each model.
