GMC Vandura 1500 Reviews
I just bought my 1st van a 1995 Gmc Vandura 1500. I'm starting my moonlight plumbing biz and realized little ford focus could only carrie a couple bucket's worth of tools and my wife was getting tired of me beating up the family Chevy venture for the past couple years. I know it's not the most powerful of van's but for only $1800 and only 49,688 on the old ticker , I couldn't refuse. The body has only a few rust spots on it and some old keyed marks but over all it looks like I got a Great work horse.I'm a husband and a father of three amazing kids hopefully this investment will help me take my side biz to my main biz, so I can provide even more for my wounderful family. Ya , some people my say it's just some old van but it's my old van and I'm proudly going to use it each and every. Thanks GMC, THIS 17yr old Vandura is getting a new lease on life!
