And they'll also do their best to extract as much money from you as possible for that car. I'd say search for some good deals on sites like CarWow and DriveTheDeal first, then you can go to your local dealers and see if they can compete with those quotes.
Have you test driven both cars? Make sure you do that before talking money with the dealer. You might not like the hard ride of the ST, or the ZS might seem too slow in comparison, so you might be able to decide which one you want just from a test drive.
Thank you for this. I have test driven both. I do like the ST though it is a little too much for me to justify each month.
