Truck Stuff
I closely considered the XC 90. Great looks & build quality. Excellent driver - solid as a vault. But the same ole' Volvo
traits were there: high price [compared to 4R], and down on power, unless you consider the turbo, which then makes the $ harder yet to swallow. I'm not dissin the XC 90, or Volvo; you asked 'why' and this is why I'm not in one.
X5: FOXY, great handling, & quick - if you go 4.4. End of good news. Bad news: Poor off road, impractical for anything other than four passengers, & get the gun price.
ML320 : Not much to like here. Quasi-affordable, austere inside,
funky looks. Poor off road. If you're ok with funky looks [ok, maybe 'different'] I don't see how there has been one single ML sold since the FX 35 hit the ground. Cheaper, gorgeous interior, excellent handling, & quick. Again, no off road.
Just MHO, here, but worth the price.
