It's possible, though illegal and not likely that a reputable dealer would do it. The later models of vehicles are made to prevent tampering, however older ones can be easily changed. If you are suspicious, look for signs of higher mileage such as excessive wear on the gas pedal and brake, arm rest, and steering wheel.
depends on the mileage and its condition
you can talk to the used car dealer, and bring up the issue KINDLY, and inform him/her that there was a mistake somewhere along the line, and you felt misled. from there, it goes by what he/she and you say.
That varies according to reviews and also depending on where you are traveling and how often you drive. It is best to go to a car dealer and find out about the mileage this car gets.
it depends how nice the dealer is
If all you have done is give them a deposit then they can do almost whatever they want. If you have a contract you may have additional rights.
Only the dealer can do that using a StarDiagnosis. This will take 5 minuts
The oil change garage or Mercedes dealer has to reset the oil change light. The oil change light goes by the mileage on the car, tripping the light on at the factory recommended oil change intervals. The computer doesn't know you changed the oil in the car unless you tell it. Read your car owners manual.
Take it to the dealer if mileage is under 20K
In fact I would advise against it on a high mileage transmission.
Nope, I'm 54 and admit it. ; ) Seriously though: 1st the engine computer on modern cars will tell you the mileage if it is scanned by a dealer. So if the dash is swapped for a low mileage one you can tell. 2nd Each time a car is sold the mileage is documented by law so there are records. 3rd. It is almost impossible to change mileage anymore so it is unlikely
Yes. Usually it gets poorer as the car gets older.
The car dealer cannot take the car if it is paid for according to the contract. The dealer cannot change their mind and take back the car after the contract is signed and money has been exchanged.
