We had a 2.0 TDCI Titanium...very good car but unless you ride a monkey bike or just want to carry one bike, you need to remove a lot of bits to get the bike in upright - the roof slopes considerably inside and the seat folding seems to rob the floor height of about 3" - comparing it to the Vauxhall Zafira, the Zafira seems to drop the seats down so you don't lose headroom, the S-Max folds into an enormous space but seems to then lose a bit of headroom height.
My wife's Specialized FSR D4W bike would go in no probs with front wheel off - size small. I had to remove front wheel and saddle to get my Large Mount Vision (18.75" frame) into it.
Very comfy to drive and seemed to be very reliable. As we got rid of it, the engine was doing something funny - driving along and it would suddenly cut out - happened to my wife several times but never to me.
Tyres seemed to be ok, had to replace all 4 in the 4 years of ownership but that was to be expected. It took about £90 diesel to fill to the top from empty and would get us around 700 miles on a tank.
The petrol version will be very thirsty...
We got rid as we didn't need the size/space, but I'd seriously consider another as I really liked it.
