Here's my early FHC (#764) It was a good car, literally rust-free, and was my daily driver for 4 years until I bought my MGF.
For a Speke-built car quality was very good, and after a lot of TLC it turned out to be a reliable car. (It did still have some electrical gremlins-When the signals stopped you had to turn the second fuse up!)
I got to like the TR7 back in the late 70's when I worked for a small repair shop, and we did a lot of work on 7's fresh out of warranty.
They had few serious problems other than the rotten fan clutch, and the MGB window winder handles.
I found that the styling wasn't as dated as some posters say. Many people were astounded to find it was 35 years old.
(7's do look much more up to date in "modern" colours like mettalic silver)
