The dealership told me I needed $2600 in repairs to fix a bad oil leak on my car. I called Lange's to get a second opinion, told them the exact items that the dealership said needed replaced, and Lange's quote was less than half what the dealership wanted. Lange's also explained that they would check out the problem first to make sure I really needed the parts the dealership said. Lange's found the source of the oil leak and the repairs were less than $400 in the end. They took the time to explain what it appeared the dealership was seeing, what Lange's was seeing that led them to believe those repairs were not needed, and what they fixed instead. I've had the car back several weeks and no oil leak. Saved me big time!
