For me, it was this:
Drove my beat up 93 XJ on 33s across the country wheeling everywhere I could following my buddy's more built up truck. I watched every weakness that truck had and eliminated it when building my 98. I was the third owner (was friends with the second) and it was pretty much a mint low miles truck when I started. Fully polished HP44, D60 rear, fully-plated unibody, hybrid exocage, hydro assist, custom valved bilstein 9100 shocks, deaver springs front and rear... the list goes on. It actually drove great on the road. It still did 90 down the highway and tracked straight as an arrow, got somewhat decent fuel mileage (10 around town, 14 highway), and was built enough that I could beat the crap out of it without breaking and still drive home. Did I mention it was my DD?
The problem? Besides taking it out on the beach, I wheeled it twice a year. I had a $4000 truck with $20k into it... and it sure didn't look the part either (unless you were a Jeeper and peeked under it). Parted it out, made a good amount of money back and bought my Disco 1. I'm leaving it pretty much stock, and couldn't be more happy.
