Also be aware that even if you buy comprehensive insurance for an old car (don't do it), they won't actually cover anything useful.

If there is an accident, the insurance company will say: Your car is only worth $700 per blue book value and your deductible is $500 so here's $200 and your title is now totaled.

Buy liability only and self-insure for any damage (or just buy a new beater as needed).
