Right I went opposite way from Fabia vRS to 182, and I definitely wouldnt go back.
The vRS is a nice car. And there is a certain novelty at first to the shove in the back it has as well as the overall quality, comfort and ride quality.
But believe me, after a few months when you are out on a country road, it will frustrate with its lack of feedback, poor brakes, an engine than runs out of puff far too early and makes little in the way of a decent sound. Its not satisfying to drive hard at all. It gives its best under normal driving really.
No doubt in my mind the Fabia is a decent car and it does have a certain charm when you first drive it, but that wore thin for me just months after getting it. As a serious drivers car, theres just no comparison between a vRS and a Cup / 182.
Oh and did I mention its not all that economical... many owners will tell you they get "60 MPG and I thrash the nuts off it". Let me tell you now, that is pure bullshit. You'll get more like 35-40 if you drive fast. I regularly had it into the high 20's and early 30's on B-roads. On a country road thrash its no more economical than a Clio.
Sure there are lots of tuning options because a lot of other VAG parts are just straight swaps. Yes you can go for a chip and it'll make it faster, but it wont change the engine note (still crap) and the intercooler will heatsoak reducing performance over long drives. The brakes are too puny for the car and the suspension is poorly damped and barely able to cope with the standard power. The power is difficult to put down in the low gears and that'll be even worse with a chip. Its not as cheap to modify as you think because its hard to stop once you start and theres so many areas needing improvement. For me that means the car is deeply compromised out of the box.
Sure it had good reviews, and by and large I agree with them IF you want a sensible car and plan on just normal drives and whatnot. However if you want an exciting car, it'll leave you wanting more in the long run.
Its up to you, but I think if you do it, several months down the line, you WILL regret it if you are a keen driver. I had a choice between spending a few grand on mine or getting the Clio. I knew it wouldnt deliver what I wanted, and with the Clio its easy enough to put up with the relative lack of torque because if driven right its not really any slower it just needs to be driven right.
As always, each to their own, but it amazes me how many people w**k themselves daft over this car, yet I had one and I liked it but didnt see what the fuss was about.
