We have a Rapid Spaceback, 1.6tdi (2014). The basic one, so basic 15" wheels/tyres(not rubber bands).
£30 VED, 50+mpg normal mixed mileage around Brum (when my wife does most of the driving, I've managed 60 - 65 around town with a very light foot!), up to 65 on a run (that's the corrected mpg, not the display). More if you make the effort.
Best thing to do is measure the ength of the bike fron the front for tips to the end of the tip of the rear mudguard, add a couple of inches and take a tape measure when you look in the showrooms!
I can get my tourer in the back easily lying down, with both front seats where they need to be (obviously front wheel removed), but I haven't tried tying it upright along one side yet like I used to do with the Golf IV or the Astra estate. (With these I managed trips to France with 2 passengers, luggage, and bike strapped upside-down on one side with just one half of the rear seat down, both wheels removed).
Tailgate is almost the full width of the car, so you get plenty of room to manouvre.
Just wish I had one of these when I commuted 300 miles/week up the M5, M6 and M54 - but then these cars didn't exist then.!
The Rapids aren't very trendy so some bargains to be had, especially used in the car supermarkets but even at the main dealers.
Check the engine outputs carefully - some manufacturers are going for smaller engines that apear to have the same bhp but the pulling power is poor, as my neighbour has found with his Focus which is a dog when it comes to hills! And if you are thinking of towing, look very carefully at the towing limits, some versions of the same car are not approved for this at all, so you can't fit a towbar even if its only to support a bike rack.
