Bloody L, where to start....

OK. In the beginning (1986) two Stratos rep kits came out. One was the Transformer, the other was the Allora. The Transformer was a more faithful copy of the original while the Allora, although also taking its body moulds from a genuine car, was more of a homage than trying to be a faithful copy. The Allora sold 14 cars before the company went under, and it was bought by Steve Greenwood who renamed it Litton Cars, and the cars themselves became the Corse, with a totally redesigned chassis. The Transformer, meanwhile, was doing very well with those who wanted to replicate a Stratos as closely as possible.
Anyway, time passed and Transformer became Hawk (same cars and people, just a name change) and Steve G sold the Litton project to Hugh Carson, who carried on with the Corse, but the company was now CAE. Eventually Hugh sold up and the firm became Napiersport, in about 2004.
Fast forward to 2010-11 and Craig White started ListerBell with a completely new take on a Strat rep. Although influenced to a degree by the Corse, there was a whole new chassis and body moulds made to a very high standard, with bespoke suspension and many other parts. The aim was to create a Stratos for the new century using modern components, a sort of "restomod" approach (but obviously not using an original car as a base). This idea seems to have struck a chord with lots of people - previously folk were more interested in making an exact a copy of an original car, but these days there's room for both camps. And all this time, Hawk have continued to make their cars, with a few mods here and there as time went by.
In the last few years Stratos reps have come to be sought after by serious collectors, with the result that prices have shot up. All of them are (or can be) worthy cars, but the quality of the build is everything. You really need to try and see examples of each of them if you can, and you'll have your own ideas about what sort of car you want to build. If it's a close replica you want you'll be looking at a Hawk, but it's a kit from the 80s so not the easiest thing to build. If faithfulness isn't that important then it'll be the others, but remember that none of them, hawk included, are true copies - they all use a steel spaceframe chassis with glassfibre bodies, where an original had a steel centre tub. Although saying that, Hawk have just brought out that very thing, if you're suitably minted...

There's a lot more to be said about all these cars, but this'll be enough to get you started. Try and get along to a garage day that some members occasionally hold - there are always several cars at them - or even the club AGM at Stoneleigh. They're a great place to meet people and get inside info , and also to realise what sad bastards we all are Meanwhile, I'm sure others will chip in with more details.
