Bristol Bullet —
The Bullet marks the return of the Bristol brand. Designed with a clearly retro look, it'll cost around $330,000.

Bristol Bullet —
The fins above the rear lights are designed to echo the design of another of Bristol's previous models, the 402.

Bristol Bullet —
The cabin mixes traditional craftsmanship and high-quality leathers with the latest touchscreen technology and smartphone connectivity.

Bristol Bullet —
The Bullet may have a classic roadster look but it's made out of modern, lightweight materials like aluminum and carbon fiber.

Bristol Bullet —
The BMW V8-powered Bullet can get from rest to 62mph in just 3.8 seconds, matching many supercars from more established brands.

Morgan Roadster —
It's hard to believe it, but the Morgan Roadster is an existing production car, produced by a British car company that's only slightly less eccentric than Bristol was in its heyday. The car's construction is a mix of steel, aluminium and ash wood (yes, really), and its V6 engine is enough to take it from 0-62mph in just 5.5 seconds. Traditional manufacturing techniques mean the average wait for a Roadster is around six months.

Morgan 3 Wheeler —
If you think a four-wheeled Morgan is a bit, well, normal, the firm will gladly sell you one of its 3 Wheelers. Not luxurious in the traditional sense, but certainly for eccentrics, the 3 Wheeler mixes a motorcycle engine with one-wheel drive. There's a healthy waiting list and the firm recently proposed an electric version.

Aston Martin V12 Vantage S Roadster —
Aston Martin's V12 engine makes some of the most characterful sounds you can hope to hear coming from under a bonnet. And squeezed into the company's smallest model, the Vantage, it makes for a really serious performance car. The drop-top Roadster model can crack the 200mph mark flat out (201mph, in fact), but even when it's cruising along, the V12 Vantage can rely on its terrific exhaust noise, sumptuous interior and achingly pretty styling.

BMW M6 Convertible —
The BMW 6 Series is the firm's luxury two-door range-topper. But when the performance experts at M division get hold of it, it turns into a seriously rapid one as well. The V8 twin-turbo engine has 552bhp and if you tick a few extra boxes on the options list, you can have the 155mph speed limiter deactivated for a new maximum of 189mph.

Ferrari LaFerrari 'open-top' —
You know a car is special when it has sold out before you even unveil it - and that's precisely what happened with the open-top version of Ferrari's LaFerrari hypercar. Well-heeled enthusiasts were shown the car at private viewings, securing enough orders to fill the production schedule long before the first official picture was released. Ferrari has yet to confirm final specs, but we do know it'll have the same petrol-electric hybrid engine as the 'regular' LaFerrari, with 950bhp, so it won't be slow.

Maserati GranCabrio —
Maserati is one of the most iconic brands in motoring, and its four-seat convertible, the GranCabrio, is one of the most potent drop-tops out there. Its 4.7-litre V8 engine -- in effect a motor 'borrowed' from sister company Ferrari, then reworked -- has 434bhp, enough for the car to reach up to 180mph.

Mercedes-Benz AMG S 65 Cabriolet —
Merc's renowned tuning house AMG takes the vast S-Class drop-top and slots in a vast twin-turbocharged V12 engine producing 621bhp and enough torque to tow a battleship. There are acres of leather on board and, unusually for a drop-top, enough space for four adults. If you go for the optional higher top speed, even that is restricted to 186mph; the S 65 would have plenty more in the tank beyond that.

Rolls-Royce Dawn —
Few cars can match the pure opulence of a Rolls-Royce - and the Dawn allows you to really show off how great your life is by lowering the roof. It's a super-plush four-seater, with some of the world's finest-grade leathers on the seats and a glorious chunk of wood, inspired by boat decking, that surrounds the front of the cover when the roof is stowed away. Is it fast? Rolls doesn't like to discuss performance figures, but if you do exploit the full range of the Dawn's 'Power Reserve Meter' (it's much too classy to have a rev-counter) you can expect to hit 62mph in under five seconds and a top speed of 155mph.

Alfa Romeo RZ —
One of the most dramatic-looking cars of the nineties, the RZ (Roadster Zagato), named after the iconic Italian styling house that built the car on behalf of Alfa Romeo -- was actually pretty conventional underneath. It's worth a fortune these days, helped by the fact that Zagato went bust before the planned production run of 350 cars could be completed. Just 284 were made.

Alpina V8 Roadster —
Alpina works so closely with BMW that the giant German premium marque actually makes the Bavarian family firm's reworked versions of its cars on its main production line. The V8 Roadster was a retuned Z8 -- considerably better and more exclusive although, even with only 555 examples made, it's actually one of Alpina's best-selling cars. Prices have rocketed recently; you can expect to pay more than $500,000 for a good example.
