One of the endless fascinations about cars is how they arrange themselves into so many different appealing classifications. Not the obvious stuff like body styles or price strata, but more practical groups: mainstreamers, premium cars, classics, bangers and what I can only think of as orphans.

I’m becoming more and more obsessed with orphans, the decent used cars largely forgotten by the market and thus very enticingly priced because there’s no 'premium' included. They’re perfect examples of cars whose early owners have borne the brunt of the depreciation, leaving greater 'metal' value, and frequently more 'driving' value, than anything sold from a showroom.

The principle of letting your car’s first owners pay the bulk of its depreciation is as old as motoring itself. Even the rise of the hot rod culture in the US was originally predicated on declining car values. “If you help me clean out the barn,” went the old saying, “I’ll let you have the old Model T…”.

What’s different now is the excellent condition of many of today’s low-cost cars. Compared with what we were offered just 10 years ago - let alone half a century - they are built to last, they tolerate mileage extremely well (when did you last seen an engine blowing oil smoke?) and in this age of diagnostics they’re even easy to repair.
