Hi I was wondering if anyone new of a garage in the london area who would help to increase the performance of a copen. I am considering getting a copen and have driven one in the past and enjoyed it. I would like to get a bit more power though and give it a bit more of an interesting exhaust note. Does anyone know of anywhere someone would be willing to help me do this? And which is the easier engine to tune the 659cc or the 1.3l? Thank you very much for your help.
