Rx8 vs 98 corvette c5- help me to decide

Hello everyone, i just registered this beautiful forum.

I live in Turkey and here, used rx8 price is 15k $

and used 98 corvette price is 30k $

I was used 2011 alfa giulietta 170hp and after alfa romeo brera 185 hp.

Now i am thinking to buy 98 c5 or 06 rx8

I want to know positive and negative sides of both cars

I expect of a car ;

- acceleration to the high rpms
-nice handling for instant overtakings

it it worth to give 2x price for 98 c5 ?

i know there is rx8 forum but please be neutral before making comments :)

Thanks everyone.
