OK, I guess I get to be the one to step up and take the hit for the Corvair.
1) They are not prone to explosion. They are no more likely to go up in flames than any other car of that era.
2) They are not "Unsafe at Any Speed", Ralph Nader was an automotive witch-hunter who truthfully knew very little about cars, and he concentrated on some minor faults, making it out that they were far worse than they were, and that buying the car was tantamount to attempting suicide. Corvairs were as safe as any other car of that era, and safer than a great many that I could name.
3) The Corvair was a decent performer for it'* time, although as a rear-engine car, it does have an unfortunate tendency to oversteer(slide the tail out) instead of understeer(snowplow, or push out in a turn).
Truthfully, you won't have any problems you wouldn't find on any other car this age. They were mechanically sound cars, fairly reliable, and not bad on gas. That said, it probably wouldn't be the best daily driver. They were noisy, hard-riding, and extremely rust-prone.
The *-10 would be a good choice, but unless it'* an extended cab, you're going to want for interior space. I personally can't drive a regular-cab *-10, my knees feel like they're going to come apart from being folded up so tight. The other issue is that living in Michigan, and having the winters that you do, the *-10 is an absolutely sh*tty winter vehicle. No weight over the drive wheels, no traction.
The Bonnie is your best choice from any standpoint you look at it from. It'* got the fun factor, the reliability, the roominess, the power, and the driveability in bad conditions.
