good luck with the Lexus
I would have sold my X5 to some sucker if I had not found this forum where one can get help with almost any issue from the great people .
your X has 55k miles only , and you have had problems , that is a worry .
I bought a 4.4i sport , 44k miles , needing pixels , 2 door actuators ,speed sensor , valley pan , entire crankcase venting and entire vacuum systems , one valve cover gasket , rear subframe bushes ,all doors leaking water , all tyres split sidewalls .
This was an Approved Used Car from a BMW dealer , does not bode well if this is the type of shit approved by BMW .
I let my guard down on that one because I thought I could trust a BMW AUC , how wrong I was .
