I really want to put money into it but i feel like i might want to try and save up for a newer vehicle and put money on that instead, any thoughts?
You will never get money back out of what you've put in, in terms of mods etc. If you want to use it for drifting, just wave goodbye to the money because it's fairly likely going to be put on the line/wall at some point. So... Option 1 - Spend money on Genesis. Enjoy drifting it. Realise it's getting rough but you still enjoy it. Buy 2nd Car and keep drifting Genesis. Option 2 - Don't. Buy new car. Realise it costs too much to drift. Put money into it anyway. Realise you should have just gone with Option 1. Option 3 - Spend money on Genesis. Don't enjoy drifting it. Realise it was a mistake. Sell it for pennies and realise you don't have enough money for new car. Realise you should have just gone with Option 1.
