Grand Cherokee srt as a fun car?

Hello, this is my first post in the Jeep Forum, as if you were lenient My last cars were all BMW’s and actually my next one was to become an X4 M40i. Last week I happened to see or heard a Grand Cherokee, the sound was awesome. Since I get a business bus provided and I want to get one for the private rides, I think about buying an SRT. The prices for the vehicles with daily registrations come to me in comparison I wanted to ask the professionals here if this would hurt the vehicle very much? What about the fuel consumption against the SRT? Are there problems due to the dimensions in the parking garage? What about the maintenance costs, insurance and tax? Sorry for the many questions, but as mentioned I did not have the jeep on the screen. Thanks already for your tips.
