Sleeper car for races

I have always wanted to build a sleeper car with my father, yet we have always been lacking the funds to do so, I have attempted to sell my possessions, such as my pc, yet I still can not get close to R50,000. At the end of the month we do not have extra funds to put away after the bills have been paid, so at this rate I don't think we would ever be able to afford to build one. This is why I have come here to ask. It has been a dream of mine to build my own car for the longest time, and I one day hope I can get this car built.

Thank you for your time.
