I agree with Legend on this. I for one do not believe in spending big $$ on a car. I drive from A (house) to B (Office) 5 days a week. On the weekend, my car is used to ferry my kids from various A and various B. To me a car should be functional and reliable and therefore does not have to be expensive. I am not into expensive aesthetically pleasing cars. A car is just a car!
I drive a honda CRV and have for 7 years and I think it is the best reliable car I have ever driven.
Now when it comes to watchs, this is where I enjoy myself. The aesthetics come into play and I am happy to spend all my money on reps and gens. Letting me enjoy looking at it strapped around my wrist. Now that is more appealing to me.
So in a nutshell I dont believe in the expensive car expensive watch ratio. I don't think they are linked at all.
