for the most gorgeous cars in the world ever, I vote as follows :-
Ferrari 456GT Porsche 911 Turbo (last of the aircooled ones) TVR Cerbera mid 60's Alfa GTA Alfa concept car (was it called the Brera or something) Aston Martin Vanquish. E type Jag (S1 3.8 roadster) '68 Dodge Charger R/T (although this could have been caused by Daisy Duke) Capri RS2600
for the least gorgeous cars in the world ever, I'm thinking
Allegro Vanden Plas Alfa 75 (Sorry Steve, but a wheeltrim spec 75 ain't pretty) Audi A2 (remind me of the shopkeepers wife from the league of gentlemen) Triumph Acclaim Vauxhall Astra (any one of them, I hate the lot) Reliant Scimitar SS1 BMW compact any front wheel drive Escort apart from the RS2000 Mk5 Vauxhall Belmont Ford Transit "Connect" Ford Fusion Vauxhall Zafira any Hyundai except the proper Coupé one
