Hmmmm, good point, er, because i havent got round to the wheel thread yet!! I actually like the ones it came with but they need a refurb in the autumn when i come back. Go on the Corrado forum and the heater matrix is a legendary job, for one person its 7 hours minimum and everything has to come off, dashboard, seats (for access), instrument panel you name it and the end result is a pin sized hole in the matrix. Having said that, the worst part is when the damn thing breaks, 120kmh and all of a sudden the vents chuck steam at you, zero visibility, zero G12, zero entertainment........
