Here are TG's top picks from £14m Salon Prive sale

Another summer of fabulously expensive car auctions is rumbling on. In a few weeks, colourful trouser types will congregate at Silverstone Auctions' supercar sale at Salon Prive, on the grounds of London’s Blenheim Palace for the latest dabble in super-rare exotica.

Assuming you’ve been sitting on your piggy-bank all summer in the hope of snapping up an (almost) priceless slice of automotive history, just what are the finest lots going under the hammer at Salon Prive? Allow TG.com to be your guide for ten of the most desirable cars up for grabs. Where’s your lottery win going?

Any lightweight Ferrari is noteworthy, but how does a uniquely-specced Scuderia showing just 52 miles from new grab you? This box-fresh example is expected to pull in between £200,000 and £230,000 – money which just a year ago would’ve gotten you into a new Ferrari 458 Speciale.

The hefty estimate isn’t just down to this Scud’s as-new condition – it’s also the gorgeous spec. No other 430 combined Grigio Merdio paintwork with a red Alcantara interior, garnished with lashings of carbon fibre. So much cooler than the obvious red with a stripe, don’t you think?

Just 75 of this particular handbuilt aluminium bodystyle were built, powered by a 4.9-litre engine that’d haul the R-Type to 120mph. Gorgeous, and a snip at an estimated £1million.

With its estimate set at £170,000-£190,000, you’re not going to have much change left for track days. Which is a pity, because this battle-hardened V12 Vantage has proved itself on the toughest stage of all, surviving multiple endurance races including two Nürburgring 24-hour outings. Missed out on the 100 road-going Vantage GT12s? you know this makes sense…

The granddaddy of today’s Porsche 911 GT3 RS, the 2.7 RS has enjoyed an explosion in value in the last decade. Small wonder this one’s expected to pull in around half a million quid. This is a Touring version, which was supposed to be the slightly more livable version of the RS, as opposed to the more hardcore Lightweight. Still, given the modern 911 GT3 and GT3 RS are sold out, it’ll have to be the old-timer…

Bad news: the new Lamborghini Aventador LP750-4 Super Veloce has sold out. But we have Good News: its Nineties’ ancestor, the Diablo SV, is up for a paltry £140,000-£160,000.

What’s not to like? Big wing? Check. Scissor doors? Gottem. Outrageous V12 engine? Present and correct with 5.7-litres and 490bhp. It’ll even do a claimed 202mph. And it’s got an open-gate manual gearbox. No amount of money can get you an Aventador with one of those...

Can you put a price on beauty? Of course you can. £75,000-£90,000, in fact. But come on, has Jaguar (with the possible exception of the Series I E-type) ever made a better-looking car than the XK120?

And of course, with a namesake top speed of 120mph, it was also the fastest car in the world when revealed.  This XK120 is a left-hooker and currently registered in Denmark, so it’s ideal for basing at one of Sir or Madam’s continental residences. We’re in love.

Only 16 examples of the most powerful, fastest Porsche 911 ever made came to the UK. This one’s done 2000 miles (none of them on track, apparently), so its 611bhp, twin-turbo flat-six engine ought to be nicely run in for you. The spec of the GT2 RS still seems outrageous today – it’s got 516lb ft, a manual gearbox, rear-wheel drive, and is good for 205mph flat out. Carrera GT pace, in a stripped 911. Less money than a Carrera GT, though, at ‘only’ £300,000-£350,000…

‘The what?’, you might be thinking. In that case, The Grifo might be the most beautiful car you’ve never heard of. A product of 1960s Italy, it combined exquisite Giugiaro styling with American muscle: a 7.0-litre Chevy V8 developing a massive 435bhp. That’s more than the V12 in the back of a Lamborghini Miura had at the time. With a top speed of 171mph, this was one of the world’s fastest cars in the early 1970s. Mind you, with this car’s rebuilt V8 offering 490bhp, breathing out through the big-bore stainless steel exhaust, TG predicts the noise alone will justify the Grifo’s £225,000+ estimate.

‘Series V’ means this is one of the final DB4s – like the new DB9 GT, it’s a distillation of all the best bits in one car before Aston moves on to the next car. This particular DB4 has a better archive than the British Museum, with forms for just about all the work carried out over its life. One of its previous owners, for instance, has installed adjustable power steering, to take the effort out of those cross-continent road trips. Well, you’d want a few mod cons for your £675,000-£775,000, right?
