Hi
The easiest way to go through things at this stage.
It all depends on the 'TYPE' of car you want, so evaluate the type of car you'd like to have and then call up insurance companies to get a range of quotes based on your specific situation. You'll then get an idea if your finances are able to cover the cost, or not as the case may be! If you find costs are high generally, you might need to think about buying a different and potentially cheaper type of car etc.
That said, some insurance companies are better than others at the time for giving quotes. You will have to shop around and use the comparison sites as well as going direct. There's many factors the insurance companies use when determining a quote for you - your postcode, age, road/driveway/garage parked overnight, driving history & any NCB, the type of car you wish to insure, anti theft devices fitted etc etc.
About 8 months ago, I called up my current insurer and enquired about a car I'd love to get and got a figure I was sort of expecting at around £1400 for the year. I called a few other places and got similar'ish amounts. I decided to leave it till later when finances would allow. I then got talking to a guy who was also fed up with insurance considering the 6 cars he has and for his business the 8-10 vans/trucks he has. We focused on one of his cars as it's the one I want too. A call to a specialist and I got a quote for £372 (limited mielage policy) for the year and once I picked myself up off the floor, I found an example I liked! Once I'd agreed the deal, I called the insurance up with the details of the car and registration number and the policy was taken out on the phone. I then made my way over to pick the car up and all was of course good as the insurance was already effective as of a few hours previously.
There's many guides about which cars in each class/catagory are good purchases as well as things to watch out for with ownership etc. I suggest you have a good look through those to help you decide on a shortlist of perhaps 4/5 cars which also fit your budget for insurance and running costs. There's plenty of places to buy and of course some are absolutely fantastic and others are very bad. I'd advise to get a pre purchase inspection on a car that you really do like/wish to buy in order that it gives you more peace of mind as to it's condition. If you do end up buying from a reputable dealer, check to see if an inspection has already been done and look at the report etc.
