We (well the wife's) are on our second now. Mainly because, with the internal cycle carrier, we can transport 3 bikes in comfort. There is loads of room, and it all sits on a compact platform. And it can carry loads of luggage if packaged well.
The first was a '56 plate 1.9 Roomster 3. Bit noisy, but good specs. But. The gearbox disintegrated at 60k miles, and there were a few other problems too. Typical VW weak points really. Good mpg though, at around 55mpg.
So we bought a new one last year, with a 5 year warranty this time. 1.6TDi SE Plus I think. The face-lifted model rides a lot better, and the engine a lot quieter. But a year old model is really good value, as they drop in value quickly. mpg is slightly worse, but a nice smooth diesel. The 1.4 TSi (105 bhp?) is supposed to be the best engine through. I would not recommend a lower power engine. Once loaded up they can be sluggish.
Apart from that, spec is good. Panoramic roof makes an airy cabin. Radio has very good sound quality. And is an easy drive, good on motorway, although the seat squabs are shallow if you are a tall driver. Simple to park and manoeuvre. They are quite under-rated due to the badge and looks. And Skoda service is very good. I . think that they are great for cyclists - not many cars have an internal bike rack that is also simple to use.
