I just recently got a kid and a raise so I am planning to get a good big diesel suv. I've been looking at the Touareg but then just realized that for
similar price there are audi q7 (basic "premium" trim) and bmw x5 and ML350 all in the 50k range.
- It's relatively "small" compared to the audi and bmw though.
-performance, and comfortableness?
So, if $50k is your range, then you can pretty much go with anything out there right now if you are ok with either base models or slightly used. I vote used in this case because you get much more for your $. For example, maybe a 2008 vehicle that had an msrp of $67,000 is now $35,000.... is that appealing, if it has only 25,000 miles and a few years warranty left, smells new, comes with new brakes, etc.? At least if you decide you don't like it in two years, you loose very little too.
Sometimes what you also get for your $ are not only a higher spec vehicle but also more total warranty time if you find the right car. Meaning, if you drive a lot of miles, then even when a car is 2 yrs into it's factory warranty, but cpo increases that to 100,000 miles, your doing better on a low mileage car having 4 yrs still and maybe something like 80,000 miles when played right. Just an idea for you to consider.
Next, if a vehicle is a total dud/lemon, hopefully it was figured out in the first year/10,000 miles.
You were correct on size comparisons, the Touareg is the smallest of all you mentioned, even the bmw. The bmw wheelbase is 115", Q7 118", VW 112". Wheelbase does not tell all of course, but it does affect handling on the highway. I'm not bashing the VW but the longer wheelbases are "easier" to relax in while at speed.
Also, the bmw with the sport suspension, not even close, way sweeter on the road and cornering. The Audi, when equipped with it's own fancy pants version, is also pretty awesome, the VW, does not have this feature available. It is just pretty good as is.
We found the Q7 headrests to be annoying. Not sure how long your drives will be, but after 4-8 hours, I am going to find what's giving me a neck ache and be rather pissed if it's my $50k-$80k vehicle!
The VW headrests were better than Q7 but nothing really comes close to the specific "comfort seats" on the BMW. 20 adjustments, including upper half of the backrest, side bolsters, ventilation, and headrests not poking your freaking head forward, also has fine adjustment headrest flaps.
Arm rests, better in bmw, ok in Audi, fine in VW, although the older Touareg had a fore-aft sliding center arm rest, very cool.
Now, sure, the Bluetech ML must have been in your obvious list but you did start this thread with "child and large suv".
What exactly is "large" about any of those listed? None of them are "large", when in the suv category. Yes, they are large compared to
some cars but not even all cars are smaller. For instance, my bmw 5 series wagon has considerably more usable space than the Touareg, yes, it really does, I've owned them both, I've measured, and fit items and the only dimension the Touareg wins is marginally in height inside the cargo area, but only by about 2". Otherwise, my wagon is as wide, wider in some aspects, longer, and doesn't have that goofy flip-forward seat issue. I can fit 4 grocery bags, 2 each side, in the 2nd row footwells with the 2nd row seats down flat. My passengers have a lot more legroom and shoulder width space than the Touareg.
I get 25-28 mpg at 65-75 mph with no trouble. Aside from towing and ground clearance, what does a Touareg have over a wagon of this size? A Mercedes E350 diesel wagon would be sweet!
Or, for an actual "large" diesel suv, the GL fits that name perfectly and it has some great aspects we liked over all the above models.
We test drove one day back to back. The best thing to do is go get one, drive it to another dealer, then drive that one, get back in the first one and on to the 3rd location, etc, then back in first one for the return. You'll either be completely confused or know exactly the right one
The GL was pretty nice depending on your needs. I think if we had a kid, plus the kids junk, and then kids friends, etc, the GL would be the obvious answer. Decent mpg, engine actually felt good for it's size, curb weight same as Touareg v6 tdi, wheelbase is 121" though.
It's seriously smooth on the highway but still turned really sharp/tight radius with ease, we were surprised. Stock tires are large (=good road hazard safety), rear hatch shape is more square so you actually get protection from rain/snow. The others slant in somewhat putting you in the rain a little more. GL tow rating is almost the same numbers as Touareg however I would see it actually more stable doing it due to wheelbase.
Used GL 07-10 are certainly in the $50k range depending on options and mileage.
FYI, 07 came standard with a full size spare and I assume this was because it was prior to "bluetech" requiring urea and thus had more room in the underfloor area?
GL has a 2nd glass roof over the 3rd row area which is sort of nice.
As for panoramic sunroofs, Q7 sucks unless you enjoy wind noise from the roof as well as radiant heat and cooling from the outside because there is only a thin mesh screen "shade" rather than an actual solid panel. The bmw has a solid panel, very nice feature.
There are many other comparisons but it starts to become more about what's important individually.
