ok heres my thought try driving it for about 30 minutes this gives the battery plenty of time to recharge if not i would keep ur cell near by when driving just in case battery is bad or alternator again
i would go for the camaro mine is 25 years old and still running strong everything is original(never been replaced) besides the tires. so thats my input
If it has a clutch then you can push start it
1>get it to the top of a hill
2>pull the clutchh allthe way in put it in 2,3,or 4th gear
3>get on the goet rollin down the hill
4>let out clutch suddenly nd then put into neutral
5>RIDE
