• Old accident damage All years One source so far

  What to check: Look for signs of crash repair, such as uneven gaps and paint that does not match.

  Sources ²

• Valve adjustment All years One source so far

  What to check: Ask for records of the valve adjustment, which Hagerty says is due every 30,000 miles.

  Sources ²

• Oil leaks All years One source so far

  Hagerty says oil leaks are common.

  Sources ²

• Worn shock and engine mounts All years One source so far

  What to check: Listen for knocks over bumps and watch the engine rock when it is revved.

  Hagerty says the rear shock mounts tend to have short lives and the S14 is hard on engine mounts.

  Sources ²

• Track or race history All years One source so far

  What to check: Ask how the car was used. A car that was raced may have been turned back into a road car, and Hagerty treats rod bearings as a wear part on tracked engines.

• Wrong wheels All years One source so far

  Hagerty says many other five-lug BMW basket-weave wheels look much the same.
