What is going on?

I have had my truck about a year now and no one has ever come up and asked about my truck. In this week I have had three different people ask to buy my truck. It is the strangest thing. The first was at the gas station; I was filling up and this guy (never seen the person before) jumps out of his car and say"Wow, I love this truck! This is what I am looking for and I want to buy it." After I told him I wasn't interested in giving up the truck (he offered $5000). He asked for my number and said he would call me later this week to see if I would accept his offer. The second person stopped me on base and asked if it was for sale and I said not really and I just had someone else offer $5000 and he said if I don't sell it to him to call him (I know this guy). Tonight I am sitting back at home watching TV and these gentlemen (I never seen either one before in my life) come to my door inquiring about my truck. Since I am not really interested in selling the truck and I wanted to see how serious this guy is I say I will take $6000 for it. He offered a trade for a 51 ford 2-door (He didn't say what shape it was in and to be honest I couln't pick out one in a crowd if I saw one) and I said I wasn't interested in another car (I am a pickup kind of guy). He took my number and he said he would call me.
What is the deal? Did the value of a clean extremely minimal rust (drip rails and pass. cab corner) 1968 short bed go through the roof? All this has happened in the last 4 days. I am beginning to think I better park it in the garage before someone get any crazy ideas.
