Which cost more: your system or your car?

It is pretty much a tie. I have a custom supercharged 800 hp BMW 540i, a daily driver BMW 535i and a week-end hauler GMC Sonoma PU. My A/V sytem cost $100,000. I love them all, and I have been blessed with being able to enjoy them every day.

My 2003 Mitsubishi Evo costs the same as the cumulative expense for my system. Then I got a Nissan GTR. I will get better speakers in the near future but still the car will be up there. I can justify 90000 for good handling at 120mph but not 50000 for an amp.

My system of course.I drive a Ford F 150 supercrew truck that I love and take care of but the system costs more.

Pefstratiou... Whenever you want to unload that GTR I'll be waiting... patiently... staring at it every night from behind a picket fence. ;-D

Seriously, if you have a picket fence then we might have a problem. LOL! j/k

My car (2010 Acura TSX) is still 3 1/2X my system at retail. But I'm just getting started.

This IMO :o) should be rephrased.
Generally on a car purchase it is a one time buy (or say 5K down and a 4-5 year loan to pay it off). Say you spend 25K on a Honda Accord - just saying. The question should be has anyone purchased a component, one time buy at 25K. If you are going to add up the cost of every component of your system, and include trade in's and a lifetime of upgrading then I think this is not a good measuring stick.
If it took someone 20 -25 years to get a system up to say 50 - 75K - then IMO - you need to add up how much you spent on each car you have purchased over those same years.
Just my 2 cents.
