Castle Garage Sale

[VooDooCC]

How long does everyone think this will last? My dilemma is that I'm going to be picking up either a buggy or truggy, depends on how much I sell everything for.
I don't race, just bash.
I'm mainly debating between the 1512 and 1518, some say the 1518 is too powerful, beings that I don't race, is there such thing as too powerful?
So, do I pick up a motor while the prices are good, hoping that it'll be the right one? or Wait until i get the next vehicle and pray that the prices are still low?

Sorry if this is the wrong place, I didn't know if it deserved it's own thread. Please move if needed.
