No Problem, None taken!
Well, you don't have to be a Genius to know that a plow puts extra stress on your vehicle! So you were told right!
I'm guessing that Lift kits (higher center of gravity), HO engines, rock crawling, and the such where your Bronco looks like you're trying to wring out a towel puts "extra strain" on the vehicle too. But that didn't deter me from buying my Bronco. Mine didn't come with a Carfax, nor was it Pre-Certified before I bought it. If we all had a Youtube highlight reel of our own Bronco before you bought it from the last 40+ years, we would all still be looking for that pristine $5000 barn find! But guess what, that doesn't exist! It's 2015, not 1994!
You seem really up on your Bronco prices and you said it yourself, there are No Broncos under $10K available on CL.
I do know that people want Broncos!
Some people actually have money and $12k to them is another mans $4K!
Most decent Broncos don't have their original engines any more! Now if you are going to play the Purist card and say that no matter what, it's a Ford and a Ford should have a Ford engine, well I guess that I would agree with you on that point! I personally didn't do the engine swap. I don't know what they were thinking, but I do know that it did take a lot of thought and planning and didn't just go down to the junk yard and buy a $75 302 out of a Maverick with 206,999 miles and sell it as numbers matching!
99% of us don't know the 1st thing about Body work, Welding and Fabrication, Engine and Trans Building and engine swapping, So a rust free (if there is such an animal), or Mostly rust free Bronco that runs good is all most of us want, or need.
Mustangs, Camaros, Chargers, and muscle cars in general have all gone through the roof!
In my mind, Bronco's are just glorified 4x4 muscle cars and It's about time that the Bronco market caught up to where it should be. That doesn't mean that I like it or condone it, it just means that I'm going to have to try harder and be more prepared when a good deal presents itself to me. And I'll get more for mine if I ever have to sell it.
In 1970 a Bronco might have sold for $3450.00.
If you buy that same Bronco today for $12000... The inflation on that $$$ is about $190 a year! Less than $16 bucks a month over 45 years.
Opinions are like A**Holes! Everybody has one!
So to answer your question, that's easy... "In My Opinion", from what I have also observed in the marketplace over the last 20 years... to the right person this is easily a 12 Thousand Dollar Unrestored 1971 Classic mostly rust free Ford Bronco!
It's clean, not dented or rusted to pieces,
It runs and drives, it stops, it's tight with little to no rattles or wind noise... AND it's a BRONCO! BooYa!
I'm not sure that any Bronco has ever been purchased for the seller's asking price? I like the haggling, and the back and forth is just part of the fun in selling a vehicle!
