Honestly, Triumphs just really never have done anything for me. Perhaps I've just never looked at the right one, but they just haven't "spoken" to me the way some of the others have.
Again, I'd love a "Big Healey" but an MG B is probably closest to it aesthetically. A Sprite/MG Midget is absolutely out of consideration just because I can't fit in one.
I have an uncle who's next door neighbor had a restored '60s 3000 2+2 roadster. I always admired it. The neighbor passed away, and I don't know what became of the car(I'd guess one of his kids probably ended up with it).
And, in the realm of "crazy projects that cost more than they're ever worth" it's also possible to shoehorn a V8 into a late model MG B roadster. The MG B GT was made in a V8 version(3.5l Rover V8), and the late 70s/early 80s roadster had most of the the same body and frame modifications to allow the V8 to fit. From what I understand, if you have a parts GT from the same era(not even necessarily a V8) you need to transplant a few parts out of the GT into the roadster and the Rover V8 will more or less drop right in. Interestingly enough, the aluminum Rover V8 actually weighs about the same as the cast iron I-4 used in the roadsters.
All these little British roadsters aren't that practical, but it's hard not to have a smile on your face when your driving one and they really are a ton of fun to drive. I have the same reaction just seeing one driving down the road. Prices are going up on them from what I've seen, but most of them are still fairly affordable.
Of course, you should always make sure you have a plentiful supply of wiring harness smoke on hand. NOS Lucas smoke is getting hard to find.
