Is a Reconditioned BMW 740i Engine Worth It? I Put Mine to the Test for 5 Years

Why I chose a reconditioned BMW 740i engine over used or replacement options. When my original engine started showing signs of wear after about 120,000 miles, I knew it was time for a decision that would define the next chapter of my ownership experience. The car still looked great on the outside, handled beautifully, and had been well-maintained otherwise. But under the hood, things were starting to show their age — oil leaks, occasional misfires, and an uneven idle made it clear: this engine wasn’t going to last forever.
