Now, you're narrowing it down a bit. The sticker shock at Snap-on is understandable if you had a <1000 budget in mind for a toolbox.
In the toolbox range you're looking at, without ordering one and paying freight, HF 44 or 56 will probably be your best bet.
If your target quality level of tools is Kobalt, comparison shop the better HF ones, Carlyle at NAPA, and maybe Williams (Taiwan quality, not USA ones) or Blackhawk sets. You should be able to find a selection that suits you in those.
As to the price of Snap-on in comparison to the others, and the quality difference: This follows the 90/10% rule: On commodity level items, you can get 90% of the quality for 10% of the price. If you want that extra 10% of quality, you have to pay 10 times as much.
You can get an inexpensive ratcheting wrench set for under $50, and the same wrench set is $400+ from Snap-on. You can buy a $20 HF ratchet, or a $140 Snap-on one. The Snap-on is absolutely, undoubtedly better. But, it is hard for someone that expects a $50 or $20 budget to think that it is $400 or $120 better.
However, if you want high quality, durability, top level design and pride of ownership, Snap-on can supply all of those. At a price. Only you can decide if the benefits are worth that price. The same can be said of most of the other quality brands. Better, yes, but much more expensive than the imported, mass produced, common retail quality level available at discount stores.
It all depends on what you want to spend your money on. I have Snap-on and Proto tools. I have a SO box, and two Shure boxes, which are heavier and better built (and as expensive) as the Snap-on. But, I don't have any car that approaches the level of cost of yours. I drive a 20 year old pickup and a scratched up, beat up 12 year old SUV, and a 6 year old mustang that I bought cheap.
