There are so many things to think about when buying a car, that it is not something you ought to rush into. One of the most fundamental decisions you’ll need to make, however, is figuring out whether you want a vehicle that runs on petrol or diesel. Both these forms of fuel have their own advantages, so it is an area you’ll need to give careful consideration to.

Petrol

If you’ve got a tight budget that you want to stick to, it might be worth buying a vehicle that runs on petrol. Such automobiles are almost always cheaper than their diesel equivalents, while annual fuel costs will also be lower, especially if you clock up a significant mileage (usually around 10,000 miles a year or above).

Those who demand a high level of performance when out on the road may also want to go for petrol cars, as these tend to provide a smoother and faster ride than vehicles that run on diesel. Petrol-powered models also tend to be slightly more reliable than their diesel counterparts and – in the event they need major repairs – can be easier to fix.

Diesel

While there are plenty of reasons to buy a petrol-run car, the benefits that are on hand when getting a diesel vehicle should not be discounted. As a general rule, these cars tend to have a greater level of fuel efficiency and, as such, can potentially cause less damage to the environment. If minimising your carbon footprint is something you are particularly passionate about, you should look for a vehicle that is fitted with a diesel particulate filter that will prevent soot-like emissions from entering the atmosphere.

Cars with diesel engines also offer greater torque at low revs, something which can be especially useful either when overtaking or towing another vehicle. It’s worth bearing in mind such automobiles usually retain their value for a greater period of time, an aspect you might be particularly grateful for if you decide to sell it in a couple of years, and are more suited to longer journeys.

When you have decided whether you would like a petrol or diesel car, there should be plenty of scope for you to find a vehicle that suits your needs. One way this could be done is by going to an auction for BMWs. Attending such sales not only means you’ll be presented with a wide array of cars, but you’ll have greater scope to get the vehicle you want at a price that is right for you. Rather than having to negotiate with car dealers over costs, you have complete control over how much you bid. You may even get a car for substantially less than you would have to pay from a traditional dealership.

If you’re hoping to get a petrol-run car, it may be an idea to keep an eye out for the 114i ES. This three-door vehicle is available exclusively in petrol and is capable of going from zero to 62 miles per hour (mph) in 11.2 seconds.

For people wanting a diesel-run BMW, the 535d line could be a great choice. While there a range of models to choose from, the 535d M Sport will certainly offer drivers a powerful ride, as it is capable of reaching a top speed of 155 mph and has a 2,993 cc engine. Choosing the 320d Sport, meanwhile, will see you drive a vehicle that is capable of reaching a top speed of 146 mph.
