If you are thinking of buying a second hand car then you may look at sites such as Gum Tree, Auto Trader and Ebay to find what you are looking for.
Many of these sites list the technical information in a table format allowing you to quickly glance at it and find out the engine size, mileage, make and model etc but there is also an area for a personalised description. Always make sure that you read any description in detail and ideally a few times as it can be easy to scan over something that states the car needs work etc without really taking it in.
If when reading the description you find that there are problems listed but the owner has stated “very cheap to fix” then I would be very dubious. Often if it really is very cheap to fix, they would fix it making the car more saleable. Never buy a second hand car without seeing it and ideally driving it as only then will you start to get a true picture.
