I work for a vw dealership and as far as I can make out the bocanegra has the same engine as the polo gti and in all fairness there shit, MOST of them have been back for new engines because the pistons just arent strong enough to take the power. if your thinking of thrashing it about all the time then definatly swerve away from them and incase you didn't know the noise is all fake, they have installed a speaker in the dashboard to enhance the noise << this is on the polo so can't see the bocanegra being any different. The golf gti on another hand, my friend has a 2.0l turbo mk5 gti and its an absolute animal, 300bhp DSG. They can be very nice cars but its just getting a good example, for 10k you can get an immaculate one. Good luck though mate
