In the 1970's, Princess Anne used to drive a Scimitar, whcih was quite a sporty car. You still see them occassionally and I love the style and shape of them! I definately agree with the Lancia Ypsilon as they're quite nifty little cars - I saw dozens in Italy!
I loved the 1970s Daimler Double Six' (not the Limousine, but the Coupé). I definately would choose a Daimler, Jaguar, Bentley or maybe another vintage car. Scimitar was also a very beautiful and dashing car!
