Yup we have an Xc90 in family and X5. MB SUV’s are trash. One gripe I have with Xc90 is their gadgets are very slow and often crash. They did a lot on my wife’s s90 and my dads Xc90. I guess first world problems.
I will have to email your dealer tomorrow to see their best price
You can always add 50 extra HP/70 ft/lb with a JB4: https://burgertuning.com/products/group-6-jb1-and-jb4-for-ea888-gen-3-252hp-4cyl-audi-porsche. I would also recommend Bluetooth kit.
Since you’re in CA, you would need to order from: https://www.uspmotorsports.com/JB4-GP6-GEN3-20328.html.
It’s definitely more fun to drive.
