Aero cars are more expensive for a reason, for example it takes almost 3 times as many man hours to assemble a rolling chassis than a trad and then there are the costs of the materials i.e. bonded alluminium tub, BMW V8, IRS, AP brakes etc...
I like to think of the Aero SS and the Plus 8 as essentially the same car, however one is wearing an Armani suit and the other is wearing a more traditional Saville Row three piece suit!
At £15k less than an Aero SS Coupe it's a bargain, just a little bit difficult to get to grips with the price as it has been slotted into the classic range.
