The bus itself is a 1994 Thomas Saf-T-Liner with an 8.3L Cummins engine and Allison 643 transmission. When we purchased it, it had around 166,000 miles. We bought it for $6,000 in New Mexico. Adam found it via craigslist, put down a deposit, flew across the country, and drove it 2000 miles back to NC. Can you get a cheaper bus? Hell, yes. But we had specific things we wanted, just like when you buy a used car, you shop until you find the things that are important to you.
