The first few years after we bought the car, the biggest vacuum leak was the shop sucking my wallet dry

. I didn`t understand the system, so kept taking it back to fix the constant, hard shifts, door locks not working or eng not shutting off.
I think it was a easy money maker for them, I drop it off, they Vacuum my wallet.
Once I found out how the Vacuum system works, piece of cake. hello mity-Vac.
The only vac problem the past 5 yrs has been the R/R door actuator. replaced that, and it`s been smooth sailing.
Now, what do I do with all this extra money?
