One reason is that what we have in our basement
My father has a 5.7L in his car, I have 5.0L in my car and then we have 2 extra 5.0L in the basement
We probably have enough stuff for Fox Body Thunderbirds (the 80's T-birds) to make the whole suspension etc and engine, tranny and rearaxle etc.
Most is performance parts though ^^
We got our basement full of engines and parts for the 2 cars, and the whole upper storage thing over the garage. Dunno what it's called in english but it's the storage place just under the roof and above the cieling in the garage ^^
