I know it's a lot of money - I saw that, and thought there is a lot in the kit too - won't fit my car, so my advice would be ----- GO FOR IT..........
PS: I have a cart full of stuff there too - just trying to pluck up the courage to buy...... so what should I do.... about the same price as yours, but loads of parts in there - no
turbo mind, so that will be extra.
