If you decide to sell the RS, it's game over for you from both sides(458 + GT3 RS) your only hope is pre-owned dept. and their farcical prices.

The lower the mileage, the higher the asking price.

Funny thing is, an F40 is now going for over 1M and nobody has any interest in it, all talk and no real buyers or enthusiasts.

458 Spider = 165,000 ~ 280,000 EUR
458 Speciale = 260,000 ~ 400,000 EUR
458 Speciale Aperta = 640,000 ~ 789,000 EUR
