I'm thinking of changing my car. Currently I have a Y reg Skoda Octavia. I'm thinking of getting something in the same sort of class as the Octavia.
Two of the more specific requirements I have are due to bike transportation.
I'm tall, all of my bikes have XL frames. In my current Octavia I can fit a bike with the wheels off in my boot, but it's tight. I recall hiring a Passat estate about 3 years ago, a larger car than my Octavia, and discovering that I couldn't fit one of my bikes into its boot in the same way. I had to take the bars off to get it to fit. Mainly this seems to be a width issue. At its widest part my Octavia's boot is pretty much the width of the car. Other cars box in the wheel wells more so their boots are narrower. I'd like a car where I can still fit a wheel-less XL bike into the boot.
The other way I transport bikes is on a roof rack. I use my roof rack and its bike racks a lot. Old Octavias have roof rack mounting points in their gutters. A lot of modern cars don't seem to do this, instead requiring roof racks to clamp through the door seals. Yuck! So any car I get would need to have a proper way of fitting a roof rack.
Beyond that, I'd be looking for a car that's 3 years old or so, i.e. another one I can keep for a decade before thinking about changing it. I know that current Octavia hatchbacks fail my second criteria and maybe the first too, though the estates (with roof rails) may be OK. A friend has suggested I look at the Mazda 6. Mondeo estates were discussed but apparently either they have nasty petrol engines or have diesel engines and have quite high second hand prices. I don't do the mileage for it to be worth paying extra for a diesel engine.
