They were/are cool cars but I was never a fan of the styling. I much preferred the TVR2500M with the same engine.
That said there aren't many cars that sound as good as a TR6 with a dual exhaust!
The other think I liked was the way the rear end would squat down when you hit the loud pedal.
I can recall the weak point being the diff mounts. We welded up a lot of them when I was working for Wembley Motors.
I got to the point where I could have a gearbox out for a clutch change in 45 minutes!
Period Piece!
