Buying advice

I currently own a 1997 BMW 528i sedan and within the next few years I would be looking to purchase something a bit newer. About AU$40,000 budget, preferably anything in the 5 series range or higher, maybe one of the X series. Any useful advice or personal experiences would be much appreciated.
Thanks.

I own a BMW X5 SUV and an Audi A8L, i previously worked for a BMW dealership here in Louisville, KY. I know for a fact that BMWs are fragile and expensive cars. My X5 is very faulty I feel as if BMW puts most of its efforts into the 6series and 7 series. They have less problems.

My spouse and i individual a new BMW X5 VEHICLE along with the Audi A8L, my spouse and i in the past labored for the BMW store throughout Louisville, KY. I realize for the idea that BMWs are generally sensitive along with high-priced autos. Our X5 is incredibly wrong My spouse and i feel like BMW applies almost all of their attempts in the 6series along with 7 string. They have got a lesser amount of troubles.
