For the average driver, an extra 10-15 mpg with Eco Pro is reasonable. It makes the car a bit less fun but more efficient. Savings add up over thousands of miles, especially at today’s fuel prices. Give it a solid test over a few tanks and see what numbers you get. Just know the performance hit comes with the territory.

There’s no definitive mileage when you must replace a BMW from a reliability standpoint. But here are some considerations around higher mileage vehicles:

• 200k+ miles is when more expensive issues like engine/transmission may start popping up in many BMWs. But not necessarily if regular maintenance has been kept up.
• If the vehicle has a thorough service history and has aged well visually, no reason it still can’t go strong for awhile.
• An older high mileage BMW out of warranty tends to get expensive to repair and maintain though. Budget for increased costs.
• Many start looking to trade theirs in from 150k miles up to 200k when repair frequency picks up or the car starts feeling worn.
• Leasing/buying new and getting a fresh warranty every few years appeals to some rather than prolonging repairs.

There’s certainly no definitive line you have to trade a BMW in. With TLC some do last and run for 300k+ miles. Do the math on your repair costs, how it drives, and other factors. If it makes financial sense to keep fixing it, drive on!
