So what *should* a budget car cost then ?
To put that comment in context if you rewind to 1986 (which I am old enough to remember) the "budget" cars of the time were the Eastern Bloc ones - the FSOs Ladas, Skodas, Yugos - most of them were using designs that were about 20 years old, were agricultural to drive (yes I had a go at a couple), desperately unrefined - even against cars like the Mk1 Fiesta (which itself was 10 years old by then) or the Austin Metro. So how much did one of those Eastern Bloc delights cost you ? Between £ 3000 - £ 4000 depending on which variant - the more expensive ones had "luxuries" like velour upholstery as opposed to vinyl and if you were lucky a push button MW/LW radio instead of a gap. In current prices that's ~ £ 7800 - £ 10,000.
The spiritual successor to those is Dacia - the cheapest Sandero is £ 11,495 - not a 20 year old cast off Fiat design, instead a modern, safe, hatchback. Bear in mind the only "mainstream" cars in those days which were less than about £ 4000 were things like the Mini, Fiat Panda or Citroen 2CV - so small, old designs and not particularly refined. Certainly not usable as a family car.
