Pretty late to this thread, but I would have to say that the most accurate replica was the continuation Mk 3 that was offered by AC cars in 1996 - 97 and imported as rollers by David Wagner.
These cars were made by the original company, in England, on many of the same body bucks as the '60's cars. Some of the original craftsmen were still there. Almost completely hand made.
I don't know if they are still available, but I inquired about one before I decided on my Kirkham, and was quoted the sum of 65,000 pounds sterling (about $105,000 US) for a roller. Curiously, during the Brian Angliss/David Wagner days, (only a few years earlier) this same roller could be had for about $53,000 US. Beautiful car, though not as practical (relatively speaking) as the Kirkham due to a somewhat thinner body.
My .02 cents worth.
