The most valuable classic sports cars we've got for sale

Are these five classic sports machines really worth this much?

These cars were the die-cast model and wall-poster fodder of their time, the ultimate playthings of the rich and famous. The cars most people only dreamt about.

We were wondering... what are the most valuable (pre-1990) classic sports cars you can buy right now? We delved into the CarsGuide classifieds to find out.

$350,000 - 1959 Jaguar XK150 S 3.4

We might have expected an E-Type or some such to make the cut, but in lieu of one being for sale, this XK150 lands a spot. It surprisingly nudges a $349,000 Ferrari Testarossa off the list.

Coming from the glorious Jag post-war days where the brand was one of the most technologically advanced in the world, it had a double overhead cam engine, in 1959! In its heyday this car would have been putting out 186kW, not shabby at all. We're fans of the green paint, drophead coupe bodystyle and period-accurate rear luggage-rack.

$388,000 - 1969 Ford Mustang Boss 429

We were mighty surprised to find a Mustang here. It's not even a Shelby, so how is it worth so damn much? The ad states that it is a genuine Boss 429.

If you're still a bit confused, the Boss 429 variant was built to Homologate a NASCAR engine in 1969 and only 859 examples were made that year. Far from being just a Mustang with a scoop, this very special car was able to put out reportedly over 370kW - although it was advertised as only having 280kW... Fully restored is really the only info offered on this car, so we can't exactly speak to it's originality or authenticity. Still, that's one expensive pony.

$475,000 - 1974 Porsche 911 Carrera 2.7

Sadly, very limited info yet again, but this car appears to be a Carrera 2.7, the first 911 model to be served up with the optional signature whale tail spoiler. It sports a 2.7-liter engine and that very nice black-on-silver colour scheme. Although it appears to be in mint condition, even the mileage has been left off of the listing. Mysterious indeed.

$699,980 - 1990 Lamborghini Countach 25th Anniversary

Actually, there are two of these for sale. The other one costs $650,000. Are the prices starting to make you sweat yet? This is the real bang-for-buck, sporting a 5.2-litre V12 with only 32,000km on the clock.

The 25th Anniversary Edition was produced from '88 to '90 and only 658 were produced making this a rare variant of a rare car. This version has even more extreme styling than the regular Countach and was the fastest, able to go 0-100 in 4.7 seconds thanks to revised body panel construction, suspension and tyres.

$849,500 - 1972 Ferrari Dino 246 GTS

This car comes with genuine Ferrari Classiche certification, and you'd hope so at almost a million dollars. The seller claims that, since this car has been restored it's only travelled ~800km but more importantly, look at that yellow paint (should a million-dollar Ferrari only ever be painted in Rosso Corsa?).

To be fair to this huge pricetag, not many Dinos exist, fewer exist in this condition, and fewer still in this condition outside of a private collection or museum. This car is likely to be so damn rare that just driving it is certain to be a once-in-a-lifetime experience. People have paid more for less.

Would you pay this kind of money for one of these cars? Is the Countach the greatest Lamborghini ever? Should Ferraris only ever be red? Let us know all of your thoughts in the comments.
