Took the wife's car into the indy shop and was floored at the issues her SAV (E70) has. 1. Turbo solenoid valve is bad, $4900 to replace the entire Turbo (BMW parts only, said aftermarket has issues). 2. Valve cover gasket again, $1600. 3. Oil pan gasket, $2300. It's a 2011 X5 35i w/ sport package (Odo: 160K) so in good condition it might be worth 10-12K. Most of it is above my skill level, only done the brakes and fluids. Repair it, or sell as is far below value?
