Just had a quick browse in your price band, just quickly picked the well knowns, must admit there is a lot of choice; but if it was me and only a weekend toy for the next 2 years, i'd be looking at the noble m12 or the TVR cerbera or Tuscan. didn't put them up but an exige would possibly go ont there as well.

But if you like the porsche and it ticks the boxes and gives you the safety net your looking for then its up to you. but i wonder if the same thing will happen to it as has with the 370. nice car but i wish it was more type thing.
as you i too have a porsche itch, i also have an alfa itch and a TVR itch. i'm currently happily sratching my V8 intch and my supercharger itch both at the same time. but i don't know what i'll do next. i'm seriously contemplating a 2 car setup where i do the alfa as a daily car and get a caterham or similiar for track fun and weekend hooning.
