I have spent the past 12 months in a 2003 A4 Cabriolet 2.4 Sport. It looks good in an understated way and has been utterly reliable. The Audi build quality is there, and rock-solid residuals make this a sensible opt-out company car. Comfort is great on good roads but can thrum and bang with the sports suspension on less than good surfaces. Heating and air-con are faultless. The boot is reasonble with the top up but be careful if you need boot space. Structural integrity is excellent with little evident flex. Bose stereo upgrade is excellent if pricey. The bad are few. The lights are poor on dipped beam, and the car offers only a competent drive, not an involving one. Acceleration and torque are very disappointing - given the engine size I would have expected better. This is where I have the reservation about my car. I have a manual and reviews have said the cvt is better, you do need to change gear a lot to get any ooomph.
I came to the A4 cabrio from an SLK - not at all the same but I have to say the Audi is by far a better car. The interior is finished to a high standard and is all reassuringly solid.
The doors close with a satisfying "clunk" and the engine is quiet and refined. The auto tranmission is blisfully smooth and the CVT means there is no jolt when it auto shifts gear. However the 1.8 can be a bit slow on the off and it's not one to leave others standing at the lights.
For long motorway driving is is extremely well suited, a very smooth ride, even with the sports suspension the bumps in the road are suitably muted but you still have a feel for the road so you are not too distanced from the whole driving experience.
The sat-nav option is well worth it, the system is very efficient and easy to follow.
Overall I think this is the best car I've ever owned.
The engines are expenisve, although the 2.4 and diesels are silly buys. Get the 1.8 - it's nippy, unlike the other 2, and if you can stretch to the 3.0, GET IT! As for the S4 - FORGET IT!
Order a brochure, find your nearest dealer or book a test drive
Amazing car, once driven, never forgotton, forget all the pretenders like BMW Z4 and Mercedes SLK, they will never have the passion of a Porsche
I love this car! Handling is great, its fun to drive and even reasonably practical!
