Honestly, with the amount the seasonals are going for now...money really isnt an issue. I made that decision (minus the DLC reason) many times for all the 15mil+ cars. You make your money back quick. Buy whatever you want...if you race and dont acquire Cr., its kinda pointless and depressing. Now, when I reach 20mil, I spend down to 5mil and stop there...then build back up to 20mil with the cars I just bought.
