if the car in good condition and stock i think better u nego nego with the dealer and buy it..from wat i see from the picture its standard for the exterior and nice exterior..
Boost goes up nicely to 0.5 bar at 3000rpm but then starts to drop to 0.3 bar starting 3000rpm until 4500rpm. After that it fluctuates about between 0.4 and 0.3 bar until 6000rpm. Any idea why? Boost leak?
