GRM: here's a 40yr old British car that weighs 4000lbs and only needs a transmission swap (sourced internationally) and solder EFI parts / carb swap / E85 conversion and has next to zero aftermarket support in this country
It may well be a cool car, and I like odd-ball performance cars, but it isn't at all what OP asked for.
There are enough track-prepped Miata of each generation that one will pop up for sale in that price range eventually.
I guess you and I have different priorities. Me, I want to go as fast as possible for the least cost.
I bought my Jag for $500. I'll have it racing for Challenge money. That's a Legitimate 150 mph car ( stock ) with 4 wheel disk brakes, 4 wheel independent suspension. Stripped down to less than 3000 pounds. Vintage eligible. With a consumable cost around that of a Miata.
Now the Miata is a good car. Nimble handling and well proven. It's just not as fast. Oh I'm sure if you spend enough it can approach the same lap times with a great driver at the wheel. But the Jag will just pull ahead from a corner and be impossible to get back around.
Not just a Jag but a Corvette, Camaro, Mustang etc. ( although those will be much more expensive )
Finally, I'll be listening to the sweet exhaust note of Thundering Elegence ( to quote Road and Track ).
