Consumer Tips
Automobile - used car test drive
DRIVEABILITY
- Acceleration should be smooth.
- Pinging may indicate a needed tune-up or may be poor fuel. Some
pinging under hard acceleration may be normal.
- Blue smoke indicates burning oil.
- There should be no delay between engine speed and speed of car.
If there is a delay, car may have transmission problems.
- If car has manual transmission, clutch should engage smoothly
and should not slip.
SUSPENSION
- When safe, take hand from wheel. Car should not pull to one side.
It is okay to drift slowly to the right due to crown of road.
- In a parking lot, make a few slow, tight turns in each direction.
Turn radio and everything else that makes noise off and roll windows
down. Listen carefully for any noise coming from front wheels that
might indicate CV joint problems. CV joints are expensive to replace
and a bad one can be dangerous.
- Remember to check for "dog tracking". The inspection checklist
explains how.
- After a quick stop, car should not rock back and forth separately.
If it does, car may need new struts or shocks.
BRAKES
- Make both slow and hard stops.
- Car should not pull to one side under braking.
- A spongy or low pedal may indicate leaks or other problems.
- Squeaking may indicate need for new pads or may be caused by
glazed-over pads.
- If car shudders under braking, it probably needs new, expensive
brake rotors.
COMFORT EQUIPMENT
- Check air conditioning for proper operation. A/C repairs and
refills aren't cheap anymore!
- Make sure heater and fan work properly. Drive car long enough
for engine to warm up.
- Check operation of defrosters.
- Make sure all power options work.
If you still want the car after the test drive and inspection
- Take the car to a mechanic and have it checked. Make sure compression
is tested.
- Attempt to contact previous owner.
