I'm in the market for a T4r. Looking for a daily driver, 2wd. I've looked at an 01 SR5 with 187K and an 04 with 188K. Both trucks have all maintenance up-to-date (timing belt on the 01; 04 is a one owner with a stack of maintenance receipts). There is about $1500 difference in the price. Most things being equal, which one would you buy and why? I guess the simple question is gen 3 or gen 4?
