I have 2 x 2008 D22 twin cab 4x4's. They have been neglected a bit. I'm now told that they need about 5-6k spent on each. (Turbo,manifold hole, and couple other bits and pieces). They have only done about 120k each and are otherwise in good nick. My question is : should I spend the cash and keep them or just trade them on some new gear? Any thoughts will be appreciated. Thx Steve
