The Max Power generation is boosting the longevity of some of motorings old-timers, according to Glass's.
The popularity amongst young drivers of cars like the Vauxhall Nova means that RVs have remained steady in the last few months.
"A standard Nova can be improved immeasurably by fitting a large chrome exhaust and lurid alloys. Squeaks and rattles from an ageing suspension can be cured by a loud stereo and a sloppy gear change can be corrected by fitting a metal gearknob. Cars like the Nova and Polo are achieving cult status amongst the young," said Chris Smith, editor of Glass's Older Car Guide.
He also said that Mercedes and BMWs around the 100,000 mile mark remain "bombproof" in the used market, bankable right up to 150,000 miles and beyond.
Diesels are also amongst the safest buys at this end of the market.
"Older diesels are still very much in demand and enjoy one great advantage over some of the newer diesels in that few are turbocharged. A worn turbo on a diesel may be expensive to replace, so remember a slower less exciting naturally aspirated diesel such as the Peugeot 405 may be a better investment."
