Hi welcome from Bristol I'm on my 3rd Z. I started with a new Z4 tin top Roadster and after numerous run-ins with the main agents I decided to get rid of what was a great car spoiled by the main agents un-helpfulness. I then bought a Z3 2.2 this was a great experience assisted by a local BM specialist and with the car not being new working on the car myself. I then went for a 1998 Z3m roadster which I still own and is a fantastic car delivering on all levels. I'm sure you will be happy with your choice, at age 65 I'm not far behind you. Best of luck Chris
