My dad is trading in his BMW

My dad has a wonderful 550i with x-drive, so it’s all-wheel drive. Its V8 engine sounds beautiful, and I love it when my dad pushes the car to perform at its best. The torque is amazing. Unfortunately, my dad is probably going to trade it in for an X5, which will have a little less horsepower. It makes me sad because the X5 won’t be able to accelerate as fast.
