I have a new username but I've been on this forum for many years, posting only occasionally. At any rate, I'd say go for a BGT if you don't plan to use it as a daily driver.

They are really wonderful cars but they do require attention and maintenance, and maintenance doesn't mean changing the oil and the points, it means paying attention to little things and fixing them before they become a problem, something every older car presents.

They handle well, and you don't need to shoehorn a V8 in them to make them fun to drive. I think frankly the TR6 is overrated as a drivers car, it looks nails and is more expensive, but relatively stock to stock I'll chase one in an auto-x anyday. I read some talking about the TD and TC, but these cars are antiquarian even compared to an A or B, that would be such a different ownership and driving experience. Personally, I have no interest in the pre "A" MG's other than looking forward to seeing a few of the models at shows and so on.

Find one with an overdrive if you can, or try to find an overdrive transmission later (which is what I did), it really changes the driving experience.

My car is an internet whore, meaning photos and specs are posted in lots of places. Don't tell her, it goes to her head. I bought it totally bone stock, put in poly bushings in the suspension everywhere, heavy duty shock valving, heavier leaf springs, an overdrive transmission, bored out 60 over with a mild cam, installed 15" (stock is 14") minilite wheels with decent rubber, put in a CD player and the amber fog lights. You can have AC installed, but it saps a lot from the engine to run it.

Maybe you are ready for:
