Hi guys, 
I'm sure similar questions have been asked previously, apologies. 
Been looking for a while at getting a Z and I've done some research but there's nothing like experience! 
So I have £7k-£7.5k to spend, mainly from a reliability perspective (but performance also), should I look at an 05 plate with say 50k on the clock or an 06/07 that's done 70k? 
  
I'd also be interested to know how the roadster is viewed in general vs the coupe. 
  
Many thanks in advance!
