The very vehicles most reviled for allegedly causing "global warming" are now being sought - at inflated prices - by British drivers taught cruel lessons by two ultra-severe winters.Some "experts" and sundry others with vested interests in the international industry that is sustained by the claimed phenomenon of "global warming" say that very warming has resulted in the climate change that blanketed Britain in snow and ice through the most recent two northern winters.The Brits probably prefer to describe it as "global cooling" after weeks of being snowed-in, their street-parked cars frozen to the roads, rivers turned into glaciers and cars, trucks and buses left stranded across the national freeway system.VALUES ALREADY RISINGThey've finally understood why the Japanese invented the mini-4x4 (to get around in that country's mountainous interior in the winter snow).The results is that British Car Auctions is warning that 4x4 values have already started to rise ahead of the first bite of winter – and will climb even further as the dark nights close in.September. BCA said, saw the value of 4x4 vehicles begin to climb sharply, the average sale value for all 4x4's sold by BCA in September reachinig the equivalent of R158 416. In August, 2011 the average value was R154 754, already up from the R128 428 of July.BCA's Tim Naylor believes anybody in the market for a 4x4 in the UK would be wise to buy now, especially if planning to travel in Europe and and to avoid being trapped by snow.“For many people – particularly those living in rural or remote areas – a 4x4 is becoming a necessity rather than a luxury,” Naylor said. "Although we had an unusually warm September, prices have already started rising and the first hint of snow and severe winter conditions could see significant demand for all-weather vehicles which will send values sky-high.” PRICES: During winter months in Europe prices for 4x4s will soar accordingly while July 2011 soar prices plummet. So what should buyers be looking for? Naylor says it's all about value and features when choosing a 4x4 though diesel models are more popular.“When it comes to choosing a 4x4, buyers should look for a high-specification vehicle to ensure it retains its value.“Alloys, leather interior, aircon and satnav all add value. Buyers also like ‘rugged’ accessories, such as mounted spotlights and a roof bar, and these accessories can drive prices up too.“Performance and torque could also be important and diesels are generally more popular although petrol does well as long as the mileage isn’t too high."He insisted, however: “Absolutely essential is a comprehensive service history. It may have been no further off-road than up a suburban kerb but it could be prudent to walk away if it doesn’t have a full service history."
