Buying a Car with Over 110,000 Miles
Many used cars sell with miles between 110K and 180K, some with over 180K miles look great and run fine, but critical when considering is asking if the following things were replaced and when. All of the following items will need to be replaced at some point because unlike engines, which can last well over 220,000 miles if cared for, the following were not made to last much past 120,000:
Timing belt (usually by 100K)
CV joints (front wheel drive cars)
CV joint boots (usually torn or ripped)
Brake rotor or pads\shoes (usually by 70K)
Heater and bypass hoses
Turbochargers (usually around 100k)
It is important to find out when any of the above items were replaced using mileage as a guide, as you might find out it is time to do it again! Maybe this is why the car is being sold? The above list may include other items.
If the oil light goes on, shut the engine off. Your engine can run with that light for only seconds. An exception is if you are slamming on brakes hard or cornering fast. In that case, stay off the gas. If the light goes off quickly, continue on, take it easy, and add oil AS SOON AS POSSIBLE!
When your TEMPERATURE light comes on, it's not as urgent as the oil light, but almost. Turning on the heater can provide additional cooling. (Your heater is just a small radiator under the dash.) A stop to let your car cool off and check out the problem can save you a lot of expense.
