Shopping for a comfy soft top 4 seat convertible with a stick. Opinions?

So here's a question for the forum...

Would you buy a new 2019 Mustang GT Premium convertible 6 speed for $8k to $10k off sticker (low $40's) with 0% for 36 months OR a used 2018-2019 with less than 15k miles for $30-$35k?

There certainly isn't a shortage of either and the discounts on the 2020's will be coming in very soon.

I'd go for used but that's my general preference on cars anyway, plus I haven't yet been in a position to afford a nice car made after about 2010 lol
