Hi, had an 8l s3 up until march this year when I decided to get an abarth 500. I am missing the power of the s3 and initially thought about getting an 8 p s3 when I'm 25 next march. After research I have seen you can pick up a b7 RS4 for around 20k! iam now considering RS4 as toy car and some 1k shed as commuter car. i have seen this question asked a fair bit but wanted to get a complete opinion from this forum; running costs; Petrol - I know it will be pricey but I'd only be doing a few 1000 miles per year so not a concern Tax - is it 2006 cars at lower tax rate? servicing - how often and what needs doing? Cam belts frequent and expensive? Any other major work to consider? consumables - what size are the tyres? Any other shockers? finally what are the common issues to watch out for? How can they be prevented? I appreciate your thoughts and advice about the above or anything else I should be aware of? I'd love to get a rs4 before I ave the weight of mortgages etc!
