That’s a very unusual pairing. I’ll take the Porsche. I’ve been in love with the 928 ever since I saw a grainy black and white spy photograph in the pages of Car and Driver back around 1976.
Among the 928 and the 131 I would pick the 131, I have driven both a long time ago and as a driver's car I would go for the Porsche, but there is likely 100 928 for each Abarth 131.
