I'd start with a big one, a 1/2" drive that goes to 250 ft. lbs. if you ever want to do your own timing belt. 200 is fine if you don't. This will allow you to torque your lug nuts to the 83ft-lbs. spec and I firmly believe that the reason my brakes have avoided the dreaded brake disk "warp" for 165K miles is because I hand torque my lugs. I'm still on original disks and second set of pads. This wrench will cover almost all suspension work.
Then you will need a smaller one in 3/8" drive for most engine work. For example, water pump bolts and valve cover bolts are both around 13ft-lbs, way to small for the big one. You want to avoid using the top and bottom 20% of a wrench's range.
I also have an inch-pound wrench in 1/4" for greater precision on the small stuff, and also for use on bicycles.
Mine are all high-quality Snap-On wrenches I bought used on eBay and then had calibrated. One was a retired US AirForce wrench, in almost perfect condition.
