Girlfriend wrecked my 04 Mustang GT (automatic), on an on-ramp for 264E in VA, the estimate from the body shop is around +2100.00 from just the aesthetics. I left work to get her and the car and when I got in the driver seat to drive it to a safer location and the engine wouldn't rev higher than 4k RPM. I lurked on google and some people say it's possibly spark plugs, but there is a severe loss of power and it would'nt shift out of 2nd. Should I expect this to be a total loss?
