Focus ST Finance

Hello together, I am currently thinking about changing my Focus mk4 for a ST X automatic, as I have been following this dream for a long time and unfortunately Ford 2025 is setting up the production of this car. All this as a new car, this would cost me 40,49€ with overpass. As a down payment I would sell my car private for about 17,000€ and put 10,000€ on it, 13,49€ remain to finance. I would pay this to 48 months to 200€ each (9600€). 90€ and about 500€ interest (currently there is a 0.99% action on interest) Now to me, I earn 1900 net, minus all fixed costs like rent, livelihood etc remain currently about 600€, sometimes more times less. I will drive in the year about 25.000km, of which 45km simply to the job. Yes I am aware that the ST will consume a little more than my current, which I drive with about 6l/100km. Due to the higher consumption and the insurance would be about 150€ more to the fixed food Is this a dream that can be fulfilled or should I rather let it be and continue my journey? LG
