Car buyers' guide Parker's is telling its readers that today is the best day of 2009 to buy a new car.

The car buying advice website www.parkers.co.uk says price cuts, stock availability and bonus-chasing dealers make March 23 the ideal day to do a deal.

Like the AM Buy A Car campaign, it points out that there are an unprecedented number of offers on new cars, and that used and new car prices will rise this summer as stocks re-balance in line with demand.

Kieren Puffett, editor of Parker’s, said: “The car market is unlikely to see another March like this – there are thousands of bargains out there. But there are signs this won’t last forever.

"The used market is picking up, stocks of cars will soon be run down and some manufacturers will raise their prices by the end of the year. We reckon there won’t be a better car buying day than March 23rd.”
