Saw the latest issue on the news stand today (I was in too big of a hurry to wait at the cashier) and while I love the "Then versus Now" tests run by many car mags, I am puzzled by the choice of vehicles for your article. Many folks consider the Lotus Elan to be as much of an inspiration to Mazda as the "typical British sports car" so why not an Elan and Miata comparo? For that matter, why not compare an older Lotus to a newer Lotus, as was done with the Porsches?
BTW, I know it isn't sold here, and therefore it would be impossible to do a comparo, but the MG TF is on sale in Europe. Now there is truely a car that has "come a long way, baby" from it's namesake.
