Craigslist is all over the place with prices. And characters. Beware.
I've been into 60s for about 20 years, and 40s for about twice that time. I've seen them go from "I can't GIVE IT AWAY" to folks asking stratospheric, VERY ambitious money for them.
In my opinion (mind you, this is me- an old school Cruiser guy), no one should be asking that kind of money for a 60.
I believe the $20k range is reserved for only the most original, cleanest, VERY low mileage examples out there. I'm talking about a 10 out of 10 interior with an intact dash/no cracks, a 10 body, and all original (including smog equipment) underhood with no more than 125k on the odometer (original, nothing rebuilt). The frame would be So Cal clean as well. These ARE out there, and people ask that kind of money. Ask. Remember that.
All the rest are in various stages of aging, damage, modification, and so on.
Its value after everything is in the eye of the beholder when it comes to these things. I have seen that.
I bought a one-owner garaged 1986 FJ60 in 2004 for 900 bucks. It was blue and had 132,765 miles. Totally original, had some wheelwell lip rust, but clean otherwise. It came with ALL the service records and paperwork.
How? Well, the single mother original owner bought it new, and used it for 18 years. After me running into her around town for 5-odd years asking about it, she decided to pay it forward since she filled her purpose for holding onto it for that long. Luck plays in at times, and compassionate people at others.
I had a friend who gave me free parts, and even trucks at one time. I had no space and had to turn them away! But I digress.
My best advice for new Cruiserheads is to come on here, check things out everywhere around the forums.
Bring your thick skin, because we have all kinds here. International people too, so imagine the diversity of opinion, age, experience, so on...and most of all, it's a writing media, so, like text messaging you can't take stuff in a blanket way. All of us write our language, feelings, and culture differently.
This is a great site, all in all. This now should probably be in the chit-chat area, lol.
So finally- keep your eye out and as time goes on you will learn more and more about the type of truck you love and be able to weed out what you don't want.
Anything else, please ask! I'm always here lurking as well.
