It’s important to tell DVLA as soon as you selling a car or you’ll continue to be responsible for paying the vehicle tax or penalties for the non-payment of it. You may also receive mail relating to motoring offences committed in the vehicle. When DVLA has been told, you should receive an acknowledgement letter confirming that you are no longer responsible for the vehicle. Important points to consider when selling a vehicle
There are some simple steps you can take to protect yourself from becoming a victim of crime when selling your vehicle:

1. It’s worth remembering that thieves can pose as potential buyers
2. Never let the buyer go on a test drive alone as they may not come back
3. Don’t leave the buyer alone with your keys in the ignition
4. Be careful when accepting cheques or banker’s drafts, don’t part with your car until you’re sure the payment is genuine – if in doubt, contact your bank
5. It’s also worth asking the buyer for a form of identity, satisfying yourself that it looks genuine
Registration certificate
The buyer will want to see the registration certificate (V5C) to allow them to check the vehicle’s details. You may not be able to selling a car without one. If you’ve lost it, you can get a replacement from DVLA.
Selling the car privately
You should always keep a separate note of the buyer’s name and address. You should tell DVLA using the appropriate section of the registration certificate.
If you don’t have a registration certificate you can still inform DVLA that you no longer have the vehicle. In order to do this you must write to DVLA, Swansea, SA99 1AR quoting the vehicle registration mark, make and model, exact date of sale and name and address of the new keeper.
However, you should note that DVLA records wouldn’t be complete until the new keeper tells DVLA in writing. Until they do, the police may need to contact you if they have to make enquiries about the vehicle.
Selling your vehicle between Great Britain (GB) and Northern Ireland (NI)
If you selling a car to someone whose address is either in GB or NI, both you and the purchaser should complete and sign Sections 6 and 8 of the registration certificate (V5C or V5CNI).
The V5C or V5CNI should then be passed to the new keeper for them to be able to re-register the vehicle in either GB or NI. While the new keeper will re-register the vehicle, you must also write to DVLA or the Driver and Vehicle Agency (DVA). You are still required to inform DVLA or DVA (the authority the vehicle is leaving) that the vehicle has been sold, so that you are no longer responsible for the vehicle.
Selling to a motor trader
If you transfer your vehicle to a motor trader and you have a registration certificate you should tell DVLA of the change using the yellow section (V5C/3) and pass the rest to the trader.
Remove your tax disc from the vehicle and you can also apply for a refund of vehicle tax for any complete calendar months remaining on the tax disc.
For this purpose motor trader means:
1. motor dealer
2. motor vehicle auctioneer
3. motor vehicle insurer with whom you have settled a claim for total loss
4. motor vehicle dismantler (scrap yard)
5. finance company with a financial interest in the vehicle
Providing the vehicle mileage
Entering the vehicle’s mileage in the appropriate box of the registration certificate will help in the fight against vehicle ‘clocking‘. This is where the vehicle’s odometer (speedometer) is turned back to fraudulently reduce the number of miles that the vehicle is recorded as having travelled.
Make sure that your ad contains all information regarding the body style, model, and year of your used car, as well as the engine size, color, and mileage. If the car has any minor defects, make it a point not to suppress them as the buyer will in any case find that out while he inspects your vehicle. Catchy phrases and positive aspects of the used car such as single owner, fuel economy, well maintained, and low mileage will create the required impact on the ad readers more than comments about any imperfections that can be easily fixed.
Before you decide on the text of your online ad, devote some time and think about what are the plus points which can be used to sell your car online. Highlight those features like low mileage, immaculate engine condition, new tires etc. Read other similar advertisements to collect some useful ideas. See what attracts you to them and then make sure your ad reads the same way. You have to write the ad in advance so that you will not make mistakes when listing the ad. Please know all writing is re-writing because you will get the best results by writing and re-writing the text.

If you do not want to be bothered by too many responses to your online ad, state explicitly ‘Best Offer’, ‘Final Price’, ‘No Negotiations,’ etc. Your best bet is selling car through online. Honestly speaking, there are not many newspaper readers who will be looking into the dailies searching for a used car. But the number of people visiting auto websites looking to buy a car will certainly be large in number. Further, the big advantage is your car listing will stay on the site until it is sold. When trying to sell your car online, you must follow a few tips.
