Buying an original, unrestored car is not easy. The chances are that, though it may look quite nice, under the skin it will need a lot of work. Many of the comments about buying a restored car apply to this category as well.

Additionally, you should consider the following questions. How has the car been well cared for? Where has it lived? Has it been garaged (depending on which part of the world the car has lived in, this may or may not be vitally important)? Has it been regularly maintained? Are there invoices with the car? Can you build up a picture of how the car has been treated? Has it been owned by an enthusiast? Has he, or she, been involved in club events, such as tours? This will give a good indication of reliability and the faith the present owner (or previous owner if it's a dealer selling the car) has in the car.
