It's really hard to make recommendations on tools without some background of how you will use them and your expectations and budget.
If you are just getting interested in mechanic work, haven't done it before, and don't know how much and what you are going to do, I'd recommend a limited amount of tools. Buy a HF 40" box, or similar, and buy a decent wrench set, 3/8" socket set, screwdriver set, a few pairs of pliers, and some hammers and then wait until you see the need for more tools before you buy more. I'd buy Proto, SK, or Wright if I was in that situation and had the money. If you don't want to put out that much money, read some of the other recommendations on here for import tools. I don't have any favorite import tools to recommend, I just don't use them any more because I have better alternatives that I prefer. Obviously, there are many out there that will do the job.
If you know how to do mechanic work, and just don't have tools out of some odd circumstance, then it all boils down to your budget and expectations.
If you just want to furnish your garage as a backdrop to the cars, I'd go for a couple of different scenario's, depending on what you want to project. If they're newer cars, or race oriented, and you want a tool persona to match, I'd buy a decent sized Snap-on box, and a decent assortment of wrenches, ratchets, hammers, pliers, etc to complement the cars. If they're classic cars, I'd consider buying a nice used classic box of that era, and fill it with either Snap-on, Williams, Proto, SK, or some combination thereof.
If you're a ******** user, and want the tools for that but want them all to be the same brand, I'd recommend you just put the money out and buy Snap-on, Proto, or SK. In the long run, they'll hold up the best, and you can be working instead of tools shopping.
The alternative most take here is different; the tools and their acquisition and collection and use are the hobby, and most users buy a combination of many different brands and types of tools. They take pride in finding tools that fit their particular niche of quality/cost ratio. Those users typically rely heavily on Harbor Freight and Gearwrench for their mainstay acquisitions, with a wide variety of other imported tools that they perceive some virtue over the other similar ones, "for the price". Some have no brand loyalty and just buy the best/lowest cost that they perceive, and others pick a brand like Carlyle or Toptul or Gearwrench or Tekton and go with that.
One last recommendation is if you just want the garage as a prop to show off the cars, but don't want to put out the money. In that case, buy a decent looking box from Lowes, Harbor freight, or Home Depot, and fill it with a combination of Harbor freight full polish tools, whatever looks best.
