According to our local rally enthusiasts, entry-level budget for 1600cc class rally is about 66000 USD per year.
30000 USD you will spend on a car. Its aproximate amount of money you’ll need to purshase and prepare Honda Civic (or whaterver you want).
About 6000 USD you’ll spend on each race, including spare parts, tyres, transportation and other spenditures. In our regional amateur rally cup we have 6 races per year. So this is another 36000 USD.
