I do have the budget to be able to hold both cars. My daily driver a 09 cobalt isn't to bad on maintenance costs, my e46 m3 hasn't been that bad knock on wood. I am also aware that track cars cost way more to maintain. I have herd that tires and breaks that will take the most out of your wallet. I am new to taking the car on a track so I am not sure about the other things that will cost a lot. I understand the weight shedding and the mods, but as for maintaining how much annually am I looking at?
