This is why I like cheaper tools. Yes, that means cheaper quality but it's far easier to approach taking a dremel to it. And the DIY look usually matches the stock materials better anyway.
I'd say it's an even split. Half the Jeeps on the road and on the trails are modified. On the road maybe 1/10 of Porches are modified, but on the track 90% are.
Big difference between bolt-ons vs deeper mods too.
Go to any mechanic thats been doing cars, especially if it's a focused subset of cars, for more than a few year and I guarantee they'll either have some modified HF sockets or wrenches or some home made tools. Probably don't want to cut up your SnapOff debt peonage tools, but a lot of the time they alone don't cut it.
