My BGT has been utterly reliable, believe it or not. The main reasons that it hasn't let me down yet are the Pertronix ignition and the swap to a Weber 32/36 DGV carburettor. I kept the SUs but they are in need of a rebuild so they're boxed and shelved for now. Today the weather in Cincinnati was about 75 and sunny, so the TR6 was the chariot of choice. Just did a major service and she's running sweetly. To be honest about roadsters, I prefer the TR6 much to my 450SL due to the sheer fun factor of driving a car that sounds, feels and rides like a real sports car should. I had a '65 TR4 which I sold back in January and it was a real beauty with only 17K original miles on the clock. A fellow from Minnesota came and picked it up in an enclosed trailer, as it was his "wife's birthday present" --yeah right!!
I would certainly love a Healey 3000 but they are so damn expensive these days, especially for a really nice one. I've looked at and driven some MGAs which are similar in appearance to a Healey but still don't have quite the grunt of the six cylinder car, unless of course you go for the rare MGA twin-cam which requires specialist care because those TC engines are sooooo delicate.
I think maybe I'll sell the 450SL. It's been a member of our family since it was brand new and we just refinished the paintwork in the original Glasurit Signal Red. Dunno, we'll see.....
