You won't like that:
per R&G p.143
you pay 10% of the cars price per box of damage alone for parts (Armadillo is 22.000, so 6x2.200=13.200)
The mechanic costs (Skill rating x hours x 10) nuyen
Automotive Mechanic + Logic [Mental] (12, 1 hour) Extended Test
Let's assume a DP of 12 (4 Logic, 6 Skill, 2 bonus from tools and stuff)
With bought hits that's 3+2+2+2+2+1= 6 hours of work: 360 nuyen for work
All in all you are looking at 13.560 nuyen repair bills

<<Puh, that won't be cheap. You could sooner get a new one, you know.>>
