the cars you can buy for watch prices are usually not very good cars, unless you are talking about very very special watches above $150k
Well, you've spent more on watches total than I have spent on cars total.
Your most expensive watch is only slightly less than my most expensive car - a Prius with all the bells and whistles.
Your second most expensive watch is more expensive than the first new car I ever bought. (Although I do have to agree that wasn't a very good car - it did last over 100K miles without needing major repairs, though. It was just 'basic'.)
And, of course, different people have different definitions of "very good cars". Someone who can afford a $29,000 watch would likely consider any car below $50,000 "not very good."
But if you are family of four, with a total household income of $100,000 (more than the average in the US,) spending $29,000 on a watch is not just "a luxury" - it is truly financially insane. But spending $29,000 on a car gets you a perfectly decent car.
Obviously, if you have the disposable income, it's your money, spend it on what luxuries you like! (I collect vintage computers, for crying out loud - lots of people, even here, would consider some of my purchases ridiculous.)
I consider both watches and cars to be "tools", not luxuries. So I buy the ones that meet my needs for the best price/feature ratio. (Yes, I created a spreadsheet to compare features, giving different features different 'grades' and weights before buying my most recent car.) Again, like with watches, I'll spend a
little more for "style" or "luxury" factor - but not significantly more.
