Great choice to have!
I have an almost 20 year old 996 Turbo running old Skool 700 bhp, no traction, 2WD etc and a Cup 380.
The Porsche is a very practical car, easy to get in and out of. Has two useful child seats in the back. 911’s have great storage. It’s things like cup holders, door pockets, glove boxes etc you realise you lose when in the Exige.
Now, iro of driving, no comparison. Ignoring power delivery and traction etc the first thing you notice is weight. The Exige (even in V6 form) is a very light modern car.
Most appropriate word for driving experience is Visceral.
I track both cars and they have their faffs. I have to change the exhaust over for the 380 and the Porsche chews very expensive Giro Discs!
I swapped my Evora 400 for the Exige Cup. I sold my 996 GT3 CS prior to that.
have you thought of an Evora Cup car? It’s a mid way car I think. Very fast, practical (ish), more storage but still tricky to get in and out of. Plus they sound brilliant on n WOT.
oh , and stay away from turbo 4pots (wife has a GLA45), Porsche or Merc, they are clever but not sixes!
