Check out my deal on a 2018 R I posted back in March: 2018 Jaguar F-Type R $1,098/mo
Your current numbers are better, but only slightly and I think that’s because your MF is higher. I would check out Edmunds if you haven’t already. In at least one locale, the MF is a lot lower and there is a large incentive available. Check this out: https://forums.edmunds.com/discussion/comment/5573691/#Comment_5573691
Chase required me to buy down the cap after the dealer ran my application through, so keep that in mind in case that happens to you.
Get the best deal that you can, and then just pull the trigger. The car is unbelievable and you will never regret getting it. Be ready for people to mob you with compliments and photographs.
edit: lol I didn’t realize you already posted in my thread previously.
