Well, first off, I just sold my '11 F250 diesel w/ 400hp and 800ftlb torque, and Rover has nothing in that league- not even close. However, as Josh states, neither is a 130/110 normally even remotely considered simultaneously with an Excursion/F250. And the 250 was $60k+ w/ heated and cooled seats, etc. The two markets are looking for two completely different trucks.
I have been building Defenders for many years- from bone stupid simple from spare parts to $100k+ trucks. I have to be making some choices as my body, yes my human body, is giving up the ghost and it is time for more replacement parts. So why this thread? I am trying to capture or I guess maintain my niche in the Defender arena, but with having a couple folks who help me, go from part time to full time. One of which grew up in S. Africa and was working on Rovers as long as he can remember. All that said, to build and focus on 110s, or 130s? I am on my third 130 currently, so am intimately aware of the build process and securing/modifying parts, especially body parts. However, is there a market as Josh outlines quite accurately above, to consume high dollar multiseat Defenders? Most all of us start with 90s, have kids, need to move to 110s, etc. Sadly, in the 110, after seating 5, there is either room for luggage or a couple more seats. In the 130 wagon or s/t, their is room for 8 or 9 plus luggage, aka Excursion/Suburban?Expedition EL. Many of these families enjoy the outdoors and travel/expeditions, so there is a 'need' for the room, and I believe a 'want' for the uniqueness/ruggedness of a Defender, and throw in a s/t and it becomes a great do all truck. Will it tow 20k#- no way. Will it be the only one at the soccer match- you betcha. Look around Nantucket and tell me how many 90s and 110s- then how many 130s? And finally- is it because they don't exist, or because there is no market??
In all reality, it is the same for the expedition world, except most expedition trucks house only two people, so the 100" wheelbase works great for wheeling and moving two folks with gear.
Lastly, Josh- tell your friend we can fill his needs ;-) A commissioned stretched NAS90--->130 s/t wagon 4.6 auto!!
