The thing I noticed when looking for iQ3's is there isn't that many around and less of those that are around are manual transmission. Trying to find one with certain options as well may prove difficult but if you aren't in a great rush and willing to travel for the right car you may get lucky. Have you found the Aston Martin Cygnet yet? Same car but very different. :) Don't forget the iQ3 came in a dark grey colour called Decuma Grey, they look great too. I have Eibach springs and they suit the car very well. The Toyota springs are the same spec as the Eibach ones and I often wondered if Eibach make them for Toyota Europe but not sure on that. Either will work as well as the other but fitting Toyota springs may maintain a warranty if the car has one but maybe they would have to be fitted by a dealer to keep that. The exhaust I have on my car is the standard system with the Toyota triangular tail pipe trim which suits the lower skirt very well. I have thought about a custom exhaust but as you say, it's a small 4 pot engine so it's never going to sound that great. :) Keep us posted how you get on. Craig.
