Hi and welcome to the forum.
Have a look at the post for new members in the FAQ section, there is a link to the buyers guide in there. There arent many issues and most are pretty obvious.
There are quite a few taller members on here and they seem to manage without any problems.
60k miles is nothing for these cars as long as they have been correctly serviced.
Feel free to post up if you want a local member to view the car with you. The members on here are a very helpful bunch.
