Horses for courses. As Big Al, says, what do you want.
If it is an economical 50 MPG diesel, then no.
If you want a sporty fast, road holding perfomance car, then no.
If you want a practical, intelligent 4WD car, with 7 seats (option), comfortable, easy to drive, handles bad weather with ease. Then Yes.
There are many issues reported on this site, but you have to ask why. All cars have problems and sometime indiviual cars are really bad, but go on any User Forum of any car, and I bet you will find the tales of woe. It's human nature, people will shout at anyone who listens when they have a bad experience, but seldom praise the good.
I had an S-Type Jag before the Captiva. Changed to the Captiva as I wanted something ifferent and the Jag was becoming expensive on fuel. The Jag was fantastic, but look at all the sites slating the Jag for its problems.
The Captiva is one of the best cars Ihave owned. I have had a few glitches, but nothing that any car could have (and do).
Would I recommend the Captiva. If you are buying a 4WD SUV of this class, yes. I was going to get a Mitsibushi Warrior, but the inside of that was like a tractor, even with leather seats. The rear (6&7 seats) where like a fold down deckchair. My son got in there, but had to be pulled out. No problem like this in the Captiva. The rear seats are full size seats. Ok, it's like sitting in theback of a mini, but people do that you know...
For me, the Captiva is best in class.... Ok, not a Volvo XC90 or BMX X5 or Landrover Discovery, but better than the Kuga, Santa-Fe, Antarra (same but Vauxhall doesnt have 7 seats), Warrior, etc...
