Firstly anything in this is just my opinion and experience up to now. I have now owned my S3 for 3 months and believe I have had long enough to get used to it. So basically a while back I made a post asking for your opinions on changing from my BMW 135i to the Audi S3. I posted on both audisport and babybmw mainly getting one sided views from both as expected with some sensible opinions too. Being an all round car fan if I like a car then I like it I don't have a favourite except the veyron but I can dream. So when I changed my car the usual question was "Bit of a come down aint it?" Yes this was from people who know zero about cars which was annoying at first but soon passed, although I could understad the status symbol of the 135i. To me the 135i is an excellent motorway cruiser which you can have fun with in the bends. The S3 is more of a sprint car but for all conditions. It was wierd at first because I was naturally trying to compensate for any possible back end action. However now that I'm used to the S3 I believe handling to be good but with some understeer. This could be due to tyres, Bridgestones which although they were runflats on the BMW I think their pretty rubbish on either car. The engine in the 135i is superb with loads of potential however you do get some poor throttle response at times sometimes perceived as lag. The engine note of the 3litre twin turbo is very nice but I do also enjoy the whooosh noises of the S3. The 135i lacks an LSD which should come with better tyres because it can't handle the power in even slightly damp conditions. The S3 should come with better brakes especially considering the power. The six pots of the 135i were awesome and two or three times people commented on them in the middle of traffic. The reason I bought the S3 though is the potential it holds. Once remapped with new brakes and suspension it will be an animal I believe. Interior wise I also find the S3 to be slighty ahead. I bought the 135i brand new because I just wanted it. Won't buy a new car again unless rich. Also I believe every car should have xenons and cruise control. So did I make the right choice? Yes. If you do a lot of motorway miles or can enjoy the rear wheel drive more then by all means choose that one. If like me you want to get places and push the limits then the S3 all the way especially in wet wet UK. As a further point I also think the aftermarket section is much more well supported for S3. I know its been out for longer but still the 135i has been out nearly 3 years now. As a last note I'm 23 and I think we get completely ripped of for driving nice cars in this country!! Any questions please feel free to ask. Thank you for reading. NOW I WANT TO MODIFY WHEN MONEY PERMITS!!!!
