I have a red 2010 gt cloverleaf se and know of two others, all three come up as 150 bhp cloverleaf if a number plate check ( hpi ) is run. I had mine checked on a dyno and it shows 168 bhp. A further check with alfa confirms it is an se. The alfa mechanic gave these words of wisdom " The se was an end of run model with extras to try and shift them as a new model was due . They had 170 bhp ,Q2 ,xenons ,sport button ,headlight washers ,blue and me ,condensation control. Came in red or white , no badges aside from GT on the boot , no i.d sticker on drivers b pillar"
I purchased mine from a dealer who thought it was a 150 so its worth looking at these models and as ALFADOIT says if it has a sport button its a 170 and probably Q2.
I hope you find what you are looking for Rick
