To Young and Naive:
It really depends on what you want to do with the car. $500 isnt bad considering...although, I highly doubt $3000 will get the DET installed and running, you may get lucky tho...
All of us started out with a DE and worked up from there...many a dream to get a turbo....so if your looking for a car to get you from point A to point B and your willing to invest in the repairs, go for it. You can always upgrade later...
What year is it BTW? AND if the window was busted, check the pan (floor boards) for rust not an easy thing to fix...
Oh yeah, welcome!!!
