It's not so much the budgets - it apparently only saves around $400'000 a year. They're still carrying it around, just in pieces rather than a complete car.
It's more to do with garage space. There isn't any.
but if they had a spare car they would still want all the spare parts they normall bring and i doubt it only saves 400,000 a year because a lot of parts they dont need to bring so they dont need to make.
some parts just wont ever need replacing
