well he cannt drive it with the clutch being screwie
just think about it... 1,500car valve. new car 8,000+, value of buying a used new car 6,500... the repair cost for your car id guess ruffly 500 depending on your guys shop...
REPAIR > new car purchase. end story... remember its your money, your choice.

 

where in the bay area you at i know a shop that can probably give you a good deal on the repairs well at least on the clutch issue and the leaks that you have not sure about the trailing arm but it wouldnt hurt to ask
