Buying and owning
Costs, equipment, reliability, safety and security
Few buyers will choose to pay for either car outright, but if you do, the A45 will leave a significantly smaller dent in your bank account. Not only is it a cheaper car to begin with, but Mercedes is also willing to offer a hefty discount. Audi dealers, on the other hand, were unable to offer any discount on the new RS3 at the time of writing.
The same price disparity between the two cars remains when looking at PCP finance deals. With a £5000 deposit down and a mileage limit of 10,000 miles a year, the RS3 will cost you almost £70 a month more than the A45.
Insurance premiums are higher on the RS3, too, as are fuel costs. However, the RS3 is predicted to be worth significantly more than the A45 if you sell after three years, while servicing costs are lower. All told, then, the RS3 actually works out slightly cheaper to own.
