We've got a Zafira for family duties. its perfectly adequate in most respects. if you are considering one then I’d give the following advice.
many people on here will tell you all vauxhalls are comprehensively rubbish. there are two reasons for this
1. the base spec ones you get from the rental companies are comprehensively rubbish
2. the motoring press constantly bang on about how Fords handle better (and they probably do, but I’ve never been able to perceive a difference). stick to the top spec models and they are as comfortable and relaxing to drive as any equivalent
we have the 1.9 16v cdti 150bhp engine. its pulls very well at any road speed even 7 up with a trailer and roof box. does 60 in 10 seconds and it will also do 50mpg on a run. MPG does take a hammering over 70mph. the 8v 120bhp engine is nowhere near as good and (according to my indi vaux mechanic) suffers from a number of common faults. iv e driven a 1.7d in an astra and that was also rubbish
if you get a 55 plate with the 150 engine, they come without DPF (same new shape body) you'll get a 55 plate Design/SRi/Elite with sensible miles for your budget easily
the boot isn’t great for bikes as its squared off between the wheel arches so its not as wide as it could be. it seems only the bread van derived cars do this right. the middle row fold vertically and slide forward but don’t come out, so you don’t have as much length in van mode as you would in a touran. also, the middle row needs to fold and slide all the way forward deploy or stow the rear row, which is a faff if you have car seats fitted.
we've done 100k in ours and in that time (other than servicing) its had an alternator which was a £400 job, one broken spring and split wires on the multi-plug for the rear door. a couple of the alloys have peeling lacquer on the bead so they loose pressure over a month or so - really need to get that sorted. it doesn’t use any oil between services and its pretty light on tyres. servicing is very cheap at an independent. im always surprised how cheap things like brake discs are especially considering how big they are!
you'll still need to be careful with your car seats tho - we have a pair of maxicosi something or others (for a 18month old and a 4 year old) and whilst mrs petrieboy can squeeze in between them, you wouldn’t get a booster in and access the seat belts.
at the end of the day, the touran and s-max are probably better cars, but they will be more expensive, a galaxy will offer more space for child seats bit will be more expensive to fuel and slower, a berlingo will probably be more practical but you loose a bit of refinement but the zafira offers pretty good value and all round practicality. you pays your money.........
