Why do we spend money on older cars like RS'?

I was going past a subaru dealership today and thought it worth a look.

Anyway, there was a P1 and a new WRX STi WR1 there. The WR1 just looked VERY nice. shame it was £27k...

Around the corner was an 03 reg PPP'd scooby.

I know these are scoobies, but they did look nice, and i'll be honest, if i got offered the P1 / WR1 / PPP'd scooby over a cossie, i'd of taken the scooby...

for the first time ever, scoobies are growing on me (i need to see a doctor ) Honestly tho, they dont look that bad!

So, why do we say spend £8k on a cossie, as opposed to say spending £8k on an EVO 5??

Discuss.
