In terms of reliability, how have you found Bristols?
Not too bad for a British car

The Bristols are actually surprisingly simple and straightforward to maintain, the only complications tend to be with the rear suspension (complicated subframe) and cooling issues with the big V8. The Brigand adds a bit of complexity with the turbo, but still not too bad.
One source of problems is that everything is electrical - if you have a dead battery, the only way to open the trunk is by taking out the back of the rear seat. And as the electrics get older, expect a lot of small issues.
