I think it all comes down to the cage and the time you have. Since I will be starting with a 4pt and doing the work myself, I can keep the cost waaaaay down. As I said in my thread; what’s remaining mow is driver and vehicle safety, which will run ME about another 2k. Putting me at 6 including the purchase of the car.
Keep in mind that you will still need personal safety gear(helmet, pants shirt suit socks gloves socks shoes HANS) which will most likely not be included in the pre-built car price.
Almost half my budget vies to safety gear. Having said that, I don’t think it’ll be too heavy on your pockets doing your own car. You mAy be just like me and not really have space or time to work on your car(hence my epic parts day) so just plan around that and you cAn make it happen.
Do it.
