Welcome to the forum.
Yes, like all cars some are good and some not so. However, in my experience:
1. I ignored the trade reviews online (they seemed to concern only the pre-facelift models). Instead I read the reviews from caravan owners who seemed to be delighted with the Antara as a towcar.
2. Price was a major consideration in terms of value for money. Because of the Antara's poor reviews and dated technology they never really caught on with the public. Hence, on Network Q there was a number of virtually new models for sale having been used by VX dealers as demo vehicles. I located a top of the range SE Nav with all wheel drive in a non-standard colour at a long established VX dealer in Bedfordshire. The price I paid was about 35% less than new list with a mileage of 2600 at three months old. The car was immaculate and had been cared for by the dealer, whose service was first class.
3. The SE Nav has some good features - some of which I am still discovering - and as a car for my family use I am very pleased with it after 20 months ownership. It is good to have an elevated driving position with a roomy interior. The engine clatters on tickover but it is chain-driven, not belt.
4. From the start, I took the view that as I had theoretically saved thousands on the purchase I would run the vehicle in accordance with Vauxhall's printed instructions and recommendations, including servicing at a Vauxhall dealer, and build the likely costs into my budget. There is no such thing as a free lunch.
5. It seems that the key to smooth running is to use good quality fuel at all times (e.g. Shell, Texaco, etc.). If you don't, then add an additive to the tank to keep the engine and exhaust clean. Do not use any big diesel for short hops on a regular basis - they don't like it. The DPF is a nuisance and something you have to learn to manage; these pages are full with comments about them. I believe that using the car for regular long runs at a high temperature reduces the DPF effect and the regen occurs now whilst driving on a motorway.
6. In terms of reliability, mine starts and stops when I want it to (I switch off the start/stop feature as a nuisance) and it drives steadily with an indicated average mpg of around 34 for daily driving and dropping to around 31 when towing. I try to keep to the speed limits. On the manual gearbox 6th gear is more like an overdrive for motorway cruising solo.
7. The seats are leather, fully adjustable and comfortable. Rear passengers do not complain about legroom. The aircon chills down quickly and the car is warm in cold weather. Bluetooth works fine, as does the satnav, and I have a USB memory stick
with a couple of thousand music tracks which are mainly controlled from
the steering column. The interior quality is perfectly adequate in my opinion considering that the vehicle will be crushed eventually and will never feature on The Antiques Roadshow. I should rather spend money on my interior at home; a car is just a tool to perform a task.
8. The height of the car stands above many others in a car park, which is useful.
9. Ask for the auto headlights to be reverted back to what they were originally designed for.
10. Make sure that the few recalls have been carried out (e.g. engine undertray, starter motor, etc.).
11. For a towbar installation make sure that the wiring harness runs the fridge. Also, think about a proper spare wheel rather than the spray repair gunk; there is a lot on the forum on those two subjects alone.
You will find that members of the forum are experienced and keen to help others, bless them. so don't be afraid to ask.
Would I buy another one? Probably not because they are no longer made and there are too many around that have been run badly, or on the cheap, which has caused them to be questionable. The problem is, what else do you buy to get so much for your money and lug a loaded caravan around without too much trouble? That's a difficult one. Good luck with whatever you choose. A Kia Sorrento might be alright, but get your chequebook out!
