I just purchased a BJ40 originally out of Costa Rica. I am by NO MEANS an expert, but the price I paid seemed about right for a diesel land cruiser. We'll see. I'm the only one that really cares about what I paid for it. I'm not trying to make money off mine... Definitely had some lipstick on it, but I knew that going in.
That being said - I'm working to take advantage of it's pluses - very clean frame, B diesel motor (that's a plus for me, anyway) bench seats, H41 4 speed, side vent windows, while at the same time addressing it's issues - no heater.... well. That's about the only thing that makes the older 40s worse in my opinion than a US Spec vehicle in terms of being a good driver. But that's just me and what I was looking for. I'm sure there are many valid yet different opinions.
Mine is a '75. Drums up front, same as US. No roll bar, but longer jumps seats. Adding a heater.
I've heard good things about that Mercedes Diesel as well.
Regarding the resale value of them... since you said you wanted to flip them.
- Document where the rust is/was and how it was repaired with pictures and receipts
- Add either OEM Heat or aftermarket Heat and AC.
- California is off-limits, but the rest of the country isn't ( I think).
- Have all your import documentation and do all the importing/transferring of title before you try to flip it. (this is huge in my opinion as that's a pain in the ass most buyers don't want and is too much of a question mark)
- They are more unique, which can help the value, but will probably take longer to sell as you'll need to find the right buyer
Many complain about LatAm imports flooding the market, but as an owner of one, I say bring it on! The more the merrier and it will keep the price of driver level 40s lower. US Specs will always demand a premium, but the rest of us unwashed masses, we can afford to get into a 40. Plus, diesel!
