Reading that Jaguar will discontinue the F Type in 2024 got me to thinking that new model two seater convertibles, lets say sub £100k in the European market are becoming few and far between - although I stand to be corrected - not done any research.
Even when sharing with the MX5 platform, Fiat discontinued their version, I believe because they just could not make it work financially.
Does Italy offer a two seater convertible?
Lotus no longer offer one.
Look how many models the UK had for sale in previous decades.
What have we got? Porsche Boxster, MX5, and BMW - is the Merc SL north of £100k now?
As an old enthusiast growing up in the days of the MGB etc, "two seater sports cars" and "two seater convertibles" arent the same thing. So to my mind there are only a few two seater sports cars - the absolute basic bog standard no extras 911 is £200 under £100k if they will sell you a car without extras. There is the MX5, the F type until it goes, some Morgan models, the Corvette at £80k, the Boxter and various kit cars. I wouldnt call the BMW or Merc SL sports cars.
Mind you, given that the average new car price is now north of £40k, maybe your £100k is a bit low?
