Not necessarily true!
When I saw an exceptionally clean Kubota L48 TLB on Craigslist, I jumped on it the next day.
I had been looking for 8 months!
It was 350 miles away, but luckily a friend, local to the seller, was able to check it (and the seller) out for me.
I immediately overnighted a 20% ($6,400) bank check deposit to the seller.
Now, two years later, my L48 TLB is worth much more than I paid.
In the two years since, I have seen only one close to similar, with twice the hours, no hyd. thumb, and minus several other other accessories, .... for $10,000 more!
I was the early bird,..... and caught the worm!
I have an almost like new 251 hour machine!
