Advice please
 

I guess this question will have been discussed on many occasions, so apologies but I need some Tucson advice.
I am looking at buying a 2007 2.0 crtd Tucson 4*4. There seems to be a huge range of mpg figures quoted. I've seen town mpg quoted as 22 mpg and best mpg as 32. So, I am hoping that people who have owned one of these could share their experience. What mpg could I realistically expect in town, steady 55 and on a motorway? If there are any caravaners on the forum, what is the towing mpg like?
Thank you in advance.
