I've owned my RS3 just over a year now and as you know I like doing the odd write up about the experience with the car. I thought we'd have a look at the year in numbers this time and the running cost reality of this machine. I'll explain my reasoning for the figures below so you can see the logic behind what I'm saying. Running Cost Reality - Â£1.49 per mile based on 12,000 miles) Purchase Price: Â£40,000 (I bought at 6 months old with 400 miles on the clock, invoice price new was Â£53,275) Current Value: Â£28,750 (Glass's Guide Part Exchange Price) Depreciation: Â£11,250 - 94 pence per mile (ppm) and by far the biggest cost Fuel: Â£2914 (12,000 miles at 26mpg and Â£1.38.9 per litre average) 24 ppm Finance Interest: Â£1900 - 16ppm Tyres: Â£830 (full set of Michelin Pilot Super Sports) - 7ppm Insurance: Â£350 - 3 ppm Tax: Â£270 - 2 ppm Gap Insurance: Â£270 - 2 ppm Tracking subs: Â£110 - 1 ppm Servicing Â£0 - 2 years 'free' servicing, but see the interest charge above to realise it's anything but free! Total: Â£17904 (12,000 miles = 1.49 per mile) Add the AP brake upgrade at Â£1550 and that becomes Â£1.63 per mile. Had I bought the car from new at the full Â£53,75 invoice price the depreciation so far would be a massive Â£24,525! That would mean a cost of Â£2.60 or Â£2.74 per mile if you include the brake upgrade. Once more proving that adding options - Â£13,000 of options in this case - adds little when it comes to trade in time, the options add Â£1750 to the trade in price according to Glass's Guide. Has it been worth it? Yes unquestionably. Sure sometimes the RS3 still pumps black exhaust soot across my drive and the brakes used to squeal occasionally but other than that it has been faultless and more importantly massive fun! The fun comes at a price of course and I thought people might be interested in the realities of running one of these glorious machines.
