The car can run anywhere from $5,000 TO $100,000 IT JUST DEPENDS ON THE CAR YOU WANT.
A standerd travel car if you are willing to most of the work and don't want any frills is about $5,000
I built my own long travel car with a small block chevy (not a ls engine ) with most of the goodies and all the best parts (well most of them skimp on the trans and it let me now) and I have about 45 grand in it.you can buy a good used car for around 40-50 .
it all depends on what you want the more travel and bigger the motor and the fancier the paint the more it will cost.
Speed cost money how fast do you want to GO
