I talked to this guy BIGDOGB here is his add 899758-i talked to him on monday and he said he would bring his blazer down friday and be at my house saturday-keep in mind we have not seen each others cars in person this guy has no profile which i do.i took down my add and someone contacted me tuesday evening and offered me a fully tubbed 10 sec all motor fresh s10 blazer and wanted to bring it that night he was asking 11,500 for the s10 blazer.the guy brought it down and to my surprise traded me(i had a nice 96 z28 with some motor work done-clean car) and after i did the deal i emailed big dog that night which was tuesday and explained i just couldnt pass the deal up,he was not going to drive down until friday evening,i think i gave him plenty of notice and was honest about what i did-and he even told me earlier his truck was not worth 6,500 that he was asking-no look at his add he is bad mouthing me,do i deserve that? :?:
