currently i have a 98 silverado extended cab RWD with 83,000miles and in good condition. i am looking for opinions and insight! i want, but dont really need a 2011 brand new silverado crew cab z71 4x4. i want to get this obviously because it is nice and shiny lol but also for the 4x4 when i do snowblowing in the winter with my 3 commercial blowers. also in 2-3 yrs i will be graduating from college with a degree in finance and real estate so i will need the full 4 doors for showing houses in real estate and continuing in this business. i would sell my current truck because am afraid expensive things will go wrong in the not so distant future (its 12 yrs old) and can afford this new one no problem. i just really want to see what you guys think? i really appreciate the insight and help!
