Price. Also to get the same spec where it matters it will be PRICE. For example most models do not come with an LSD unless you go M and then you are into the £40k+ band. Usually without going M you will get a autobann-barge, a soft, luxurious, cruising saloon. Not the same class of car at all.
Don't look at servicing, tyre, insurance costs either!
This addiction to MOAR POWAR! Is induced by marketing and the big car manufacturers like BMW and their dick waving with competitors. If instead you look to motorsport heritage, even your local track today, you will find that nearly all formulas have limited power and limited grip because this makes them cheaper, fun, competitive, challenging, accessible and engaging.... and the accidents smaller.
If you want to drop it from 6th to 3rd going from 70 to 110 and warp past a BMW or Audi rep mobile on the motorway because you feel your manliness was challenged by them, then don't get an 86.
If you want to feel like you are driving 100mph on a B road with the tyres chirping and squeaking, the car communicating and egging you on, challenging you, informing you of every slip and catch of the tyres, allowing you to balance between under-steer and over-steer like molding putty in your hands.... and look at the speedo and find yourself doing 42mph, then consider the 86.
