Buy cheap, sell dear that’s the motto of every car salesman and there are now classic cars that are now worth more than when brought brand new.

Experts from car history registry carVertical analysed the automotive market and came up with a list of 10 motors, that people shouldn’t sell.

Below is the complete list.

  • Alfa Romeo GTV (1993 - 2004)

Like most coupés of the time, the Alfa Romeo GTV was available with a four or six-cylinder petrol engine. Although their four-cylinder engine model has been characterized for its agility, the most valuable version of the GTV has been that equipped with the magnificent Busso six-cylinder unit.

The engine, which has become an ace up Alfa Romeo's sleeve, is a major contributor to the significantly rising price of the Alfa Romeo GTV.

A good one of these will set you back £25,000.

  • Audi V8 (1988 - 1993)

Before the arrival of the A8, Audi’s flagship model was the V8.

The car was only available with a 3.6 litre V8 engine, developing 250 horsepower.

The Audi V8 set the groundwork for the company today, a high-end carmaker and direct rival to both BMW and Mercedes-Benz. Moreover, the Audi V8 is far rarer than other equivalents.

A good one of these will cost £16,000.

  • BMW 540i (1992 - 1996)

For decades the BMW five series has been the benchmark in terms of big luxury saloon cars.

Back in the 1990s, BMW launched the E34, a car that was one level the M5.

It had a four-litre V8 engine with 286 horsepower and a top speed of 155mph.

The eight-cylinder variant was only available for a few years and as a result, it is considerably rarer than the M5.

This model is a lot cheaper compared to its more powerful brother.

  • Jaguar XK8 (1996 - 2006)

This car made its debut during the 1990s and coupe or a convertible. It offered a variety of engine capacities and comfort amenities to satisfy most XK owners.

The Jaguar XK8 was the first modern-day Jag which raised the bar in terms of quality, technology, and residual values.

People wishing to buy an XK8 must be prepared to spend at least £12,500-£16,500 for a good one.

  • Land Rover Defender (Series I, Series II)

The first generations of the Defender SUV were designed to be a multi-purpose practical purchase for those taking care of farms.

Its basic design and the ability to tackle any obstacle imaginable have earned the Land Rover Defender the status of being a very capable all-terrain off-roader.

A good one of these will set you back £25,000.

  • Mercedes-Benz E300, E320, E420 (1992 - 1996)

Mercedes-Benz produced more than two million W124s on the road over a relatively long production run. Some ended their lives in the scrapyard but others are still showing signs of life.

The E300, E320, and E420 all have the potential to become money-makers that many collectors will battle over.

They are also a lot cheaper compared to the more powerful E500.

  • Saab 9000 CS Aero (1993 - 1997)

In December 2011, the bosses at Saab threw in the towel and declare the company officially bankrupt.

Since then Saab’s have now become a lot rarer on Britain’s roads.

The 9000 CS Aero is another car that has the potential to be a future classic.

It was introduced late in the manufacturing process and was considered the highlight of the Saab 9000 series in its final year of manufacture.

This version of the 9000 had a 1.4 litre turbocharged engine, with over 220 horsepower.

It is now classed as a rare car nowadays by experts.

  • Toyota Land Cruiser

Dubbed by Toyota owners as one of the best cars the Japanese manufacturer ever produced.

The J80 managed to combine straightforward simplicity with everyday practicality, while the J100 was considerably more luxurious, designed for longer journeys but with no less talent for digging out of a muddy ditch.

Examples of these can be sold for just under £32,500.

  • Volkswagen Corrado VR6 (1991 - 1995)

An unusual look, an exceptional engine, and a commendable balanced suspension will only make you wonder why so few people bought this car in the early 1990s.

The Corrado lost out mainly because of how popular the Vauxhall Calibra was back in the day.

The value of the six-cylinder version has begun to rise in recent years, and this trend is expected to continue.

  • Volvo 740 Turbo (1986 - 1990)

Back in the 1980s, the Volvo 740 Turbo was proof that it could compete with the likes of Porsche in terms of outright speed.

The Volvo 740 Turbo's flexibility and the ability to combine practicality with performance make it an example of a car that is rising in value.

Investing in vehicles is still a concept that not everyone understands. It may look too risky for some but, with the right car knowledge, it can provide decent returns in a relatively short time.
