Just my opinion...love gassers, big block's even more and high GVWR better and +6,000 lb RGAWR best. High numeric diff gears and any type of locker (Detroit/Gleason #1, G80 #2...#2 cuz it has clutches). Large higher class tires and high aspect ratio...as that begets an apparent +8 foot dia tire when aired down.
There is no one size fits all...as mine would have most run shouting too rough a ride...ditto on the other sided of that coin with me running shouting too soft a ride...
Get whatever suits you and your calculations via your management (gambling) decision
As for investment...are you guys talking of a home loan simple interest, compounded or variable and on variable, where is the based line used for the interest variances ? Older tax laws allowed deduction of interest, but that benefit is cut. Note that as a society, we are returning to become a renters society again, so consider yourself lucky to be able to afford to own
I own my vehicles, new and used, for my use and do NOT consider resale value (residual) and they are almost worthless in the resale market when I'm through with them. Calif has a cash $1,000 buck buy back of any vehicle over a certain age...it has to be running. So that is always a min for my vehicle disposal
Learned a loooong time ago that vehicles are a depreciating proposition and best own them until they are no longer deemed repairable, or just don't want to anymore...or is a big block with direct injection full sized +8.6K GVWR with a +6K RGAWR, 4x4 Van or SUV comes along...I'd seriously consider it...
{edit}...haven't had automotive payments since 1998. Financed my 1996 Suburban just to tickle my FICO (back then Vantage) score
