Faults:

Coolant level warning kept appearing - required a visit to the dealer to update the software on the car.

Roof leak (solved with Gummi Pledge).

General Comments:

Comfort:

It's not. I'm 6 foot and the seat is just too high. Not high enough to hit the roof, but my old 2004 Vectra had a more adjustable seat than this thing.

The seats themselves are rock hard. This, combined with the narrow base of the seat, gives what I can only describe as "nut nip" (think about it). One major benefit is the heater - it is hot as hell, so you can put the top down in freezing conditions and not feel it.

Performance:

The engine is sadly lacking. The car is simply too heavy and the engine underpowered. At low revs, the VVI engine really struggles, and again, compared to a 1.8 2004 Vectra, it is sadly lacking. Just to be clear - I'm talking general "Getting out of trouble" speeds at roundabouts etc. But anything below 60 mph also counts.

Handling:

The car is too heavy. It handles corners well - but you must be really mindful of the weight in the wet due to understeer. Handling gets much better when the top is down.

Economy:

Vauxhall claim 40 MPG combined. I don't know where this testing was done, but I did a solid average of 30.1 MPG - up to 31.5 driving like an old woman. On motorways, 37 MPG is more realistic.

Appearance:

The major redeeming factor on this car - it looks excellent with both the top down and up. The proportions are excellent, and the 3 piece folding roof is a marvel to see operate.

Interior:

Plastic fantastic, and the piano black fascia looks like it was a wrong-colour replacement from another car, as the remainder of the fascia is silver and gray.

Reliability:

I didn't have the car long enough to really comment, but general research before buying one is that it is excellent. Beware of the roof however - there are very few specialists out there and costs can get really high. A common issue is with the plastic cogs stripping the gears and the wiring loom being faulty.

Equipment:

MP3 + Aux head unit. Auto wipers and lights, auto dim rear-view mirror and half leather interior + much more. Cannot complain at all about the toys in the car.

Practicality:

It's a convertible, so you are not going to get the chest of drawers in the car, but you will get 2 kids in the back of the car and some shopping in the boot.

Do not overfill the boot however; some of the complex roof mechanism is at the top of the boot, and you don't want to bash against the plastics.

Overall verdict:

I replaced the car with a 2008 Mazda 6, 2.0d and have not looked back since. The lack of power and basic comfort, combined with the economy, is a real deal breaker with this car I'm afraid.

To be clear, I also own a 1.6 Mazda MX5 from 1991, and can honestly say it is more economic, comfortable, powerful and fun.

Avoid the Twintop. Great in theory, but after about a month, the worry over the roof, the expensive fuel costs or general lack of feel in the car will make you regret it.

Faults:

Nothing- the C4 TFS was an absolute dream to drive. Only sold it as I needed a larger boot area for my dogs.

General Comments:

The Vauxhall 1.8 Design model is a refined car. It is responsive and well equipped.

The cabin area is nice with a black console. It has comfy seats, with leather inserts.
