I have driven a couple they are great cars, they are generally very reliable, but the oldest ones are 25 years old now (amazing!, much older than the British cars I bought and thought were old when I was young). Anyway, anything that old may start to have issues, but the nice thing about the cars us they kept them simple so less to go wrong.
I have been tempted to get one, but am kind of afraid I would stop driving my British car. We have several that autocross in our British club, they are quick, doesn't seem to matter what generation. But a well prepped Sprite is still very competitive with them. My TR250, not so much, but being contrarily since I can't beat them I didn't join them, I got an old Porsche 924 instead, slow but supposed to handle well.
