Continuing the discussion from Making the jump - Convince me!:
I did the same I was running a 2010 Cayman S for 2 years but it was just too nice to take on regular track days. So I sold it and bought a 2010 NC coupe. ( the one with the folding hard top) It has a BBR conversion running 207BHP and a few other sensible mods. Probably done 10 trackdays in it in 18months and much happier with cost of consumables such as tyres and brakes.
I can honestly say I prefer it as a daily driver to the Cayman, You can thrash it without getting into go to jail territory, I love the hard top / no top options and the feedback for me is better than the Cayman. You might appreciate the extra size and space in the mk3 coming from a Cayman. My MX5 NC always makes me smile even though the wife hates it LOL I am in Grays Essex if you are over this way and want a look
