i don't know if you'd consider this low budget, but because i could afford it, i do. I built the car myself with assistance of friends for the tricky bits, the original purchase included the 1 piece lift off front end in Kevlar, complete with doors & bootlid for a meer $1500. i upgraded the driveline over the years as i saw things needed attention. it's probably a big $ car now but the funds were spent slowly & wisely as it developed.
