Ok, this is purely for curiosity's sake. I have a friend who has a 2005 Silverado and here is his situation in short: His truck has many miles on it, mostly highway, and he's starting to feel like it's very sluggish, and he also needs a new transmission (or at least to have his rebuilt). So he figured that he could get a rebuilt vortec engine installed for $3000, $3000 for the new tranny, and he was thinking while doing this why not go all out, and lift the truck, get nice rims, tires etc. Anyway all in all he estimates (on the high side) that he could spend $10,000 - $15,000 on a rebuild, accessorize and customize and make his truck awesome. However, he really likes the new 2010s and the idea of better gas mileage, and figures he could have it lifted and customized within 2 years of purchasing it. My question is what would you do if you had $10,000 to $15,000 to put into a vehicle - completely re-do your own (pretending it IS necessary) or use the money as a down payment on a brand new truck? I'm not asking what you think HE should do, as ultimately it's just a very personal choice. I'm just curious as to how many like their current truck enough to keep it "forever" vs. upgrading to something new? I myself love my current truck, but I think if I had the money (and nothing else to spend it on) I would opt for a truck upgrade and work on making that my own.
