If you are buying a car, whether it is new or old, then there are certain things that you should consider before making the purchase. There are the obvious things, of course, such as ha it passed the MOT, was any previous work done on it and so forth. If you are buying an older car, then it may not pass emissions tests which seem to get stricter as each year goes on, so this is an area to look into.
Another thing to think about when buying a car is how much the potential insurance of the car will cost you. Of course there is always cheap car insurance to be found, but that said, if you are young and have bought a car with a huge engine, then you can expect to pay a premium!
When buying a car, you may want to consider if you need any finance or not. Interest rates are low right now, and some places may offer one or two year's interest free credit on a car purchase. This does not just apply to buying a new car, but some second hand dealers also offer the same.
If you live in a city, then you may want to consider where you are going to park the car whilst you are at home or at work, a if you live in a flat parking may be at a premium.
Buying a car is a big step, but with some forethought, the process can be a lot easier than it otherwise might.
