well think about it sweatheart the engine is pushed back 100mm and that means so is the gearbox so who knows if both are f*kd. they are the most expensive things on the car. the loom would be f*kd which would have fried the ecu. so motor and running gear are pretty much useless. what else on the car is really worth the money???
ive seen an engine move back, crack an engine block as well as crack the bellhousing due to impact.
best thing is to take out ya angle grinder and chop it up and see whats wrong
