dad bought one of them in late 70`s. he never used it but it was in the trunk of his grand Torino.
I used it once , all it had was for exhaust inflation. leaking exhaust but still worked well.
starters are not a $50/100 item anymore. my friends Chevy cost $1500 4 years old.
you can choose the option without cost by pressing the button or buy a $99 eliminator.
