Too many bigging them up, its not right! 
By all means get an mx5 if;
1. You are homosexual hairdresser
2. You are currently going through a mid-life crisis
3. You are homosexual hairdresser
I know 1 + 3 are the same but its doubly true. No one envies a bloke who drives an mazda and they deffinately dont turn heads! 
I envy them when i see how quick they are on track, how much of a hoot they are to drive, and how cheap they are to buy run and mod.
Plus with very little done to them (nice wheels, little drop etc) i think they very quickly loose the hairdresser image.
