Recommendations on buying pre-owned car:


The mileage on a car doesn't always dictate how good it is; a well-maintained 10-year-old car may be better than a 5-year-old neglected car. One of the main things to ask is how often the oil was changed; it should be changed once every 3,000 miles. Also, take the car for a test drive or at least hear the engine run. If you hear a clicking or popping sound when steering, the CV joints may be bad (not fun to fix). If the engine knocks or taps, keep shopping. With the engine on and the car stopped, turn the steering wheel and listen for a moaning sound. If you hear this sound, the power steering pump is towards the end of its life. To check for oil leaks, leave a piece of cardboard under the car overnight; it is common for cars >=10 years old to leave a drop or two. While driving, cars with an automatic transmission should shift smoothly as you accelerate; if the car bucks when it shifts, the transmission may have issues. Watch for black or blue smoke coming out of the exhaust.


I would be very wary of buying a car I saw on-line, only because there are many scams involving used car websites. You should always see the car in person and get a mechanic to inspect the car before you hand over any money.


Search for used car dealerships that have return policy to keep their customers satisfied.


One thing you must realize is that there is no used car factory so you may have to make some compromises. Do not compromise on safety and don't by a vehicle that has a laundry list of issues that you will have to repair yourself. 


Make safety a primary concern. Buy a vehicle that is new enough to include airbags and if possible anti-lock brakes as well.


When shopping for a used car it is even more crucial that you shop in the daytime and in clear sunny weather so that you can see any blemishes. I have seen many cars that looked good in the rain only to reveal faded paint and blemishes in the sunlight.


Be prepared. Do as much research as you can. Read reviews, consumer reports, ask colleagues and friends, compare options, gather gas consumption data on the make and model you're interested in.


Check a car's history records. This will help you to eliminate half of the vehicles from your list with potential problems. Cars that have been flooded or restored after serious accidents, those with rolled back odometers, heavily abused vehicles (e.g., ex-rentals), etc., can be eliminated after simply checking the history record of the vehicle. 


Don't buy based on what you've heard Do your own homework.


Be careful when doing the paperwork. For example, if you buy from a private owner, make sure there are no registered liens against the vehicle and that the person who signs the Bill of Sale is the actual owner of the car. Check with the Vehicle Registration Authorities to make sure the car has not been stolen.


This may be Car scam

Cars are priced far below current market value.

The seller claims to be in the military and is stationed overseas.

The posting does not include a phone number.

The seller will demand that you use an online escrow service of their choice.

The person receiving the call is referred to as a "pickup agent."

Payment must be wired to or from another country. Western Union is often requested.

The buyer or seller is very anxious to conclude the transaction.



What mileage is OK for a used car


In general, it's not recommended to purchase a car with a very high mileage, for example, 150,000 miles and higher would be considered very high. However, "low mileage" does not necessarily mean it's going to be a "good car". Be aware of cars that may have undergone restoration after a serious accident or cars that haven't been property maintained, or cars that may have had their odometer rolled back - nowadays they can easily manipulate even electronic odometers. Again, checking a car history records will certainly help to avoid those lemons with "fixed" odometer.
When considering the 'mileage' count, its simply means that when choosing a car whether it has 60,000 or 80,000 miles, is not as important as the fact that it was well maintained and has been accident-free.
