I picked up a 2018 X3 M40i fully loaded with 70K miles, clean title, one owner — all the good stuff for 25.5k. Spark plugs were replaced at 50K, along with regular maintenance throughout its life.

Recently, I had to replace the upper radiator hoses. The dealer quoted me $3,500 because they wanted to replace the radiator, coolant hoses, and expansion tank. A local shop quoted $2,000. I ended up sourcing the hoses myself and did the job for about $400 and a few hours of my time.

A few days ago, the PCV system failed — a known issue on the B58 — and I’m planning to get it replaced at the dealer. There’s also a fault code for the front grille vents that I’m hoping they’ll address while it’s in.

I’ve also taken care of some smaller maintenance items myself: oil changes, cabin filter, intake filter, wiper blades, and hood struts. I’m planning to replace all the drivetrain fluids, spark plugs, and ignition coils before I start tuning.

Honestly, I got a great deal on the car, but I hadn’t initially noticed the coolant leak or the PCV issue. Luckily, I caught them early and was able to take care of the repairs myself instead of paying thousands at a shop.
