More than two million cars were sold in the UK last year, 1.8 per cent more than in 2009, a report showed today.
However, the motor industry expects to face a difficult few months because of the "extremely challenging" economic conditions, it added.
The Society of Motor Manufacturers and Traders said sales rose by 35,847 in 2010 to 2,030,846, but it was a year of two halves following the end of the car scrappage scheme in March. Sales surged by almost 20 per cent in the first half of the year but fell back by 13.8 per cent in the second six months, today's figures showed.
Paul Everitt, chief executive of the SMMT, said 2010 was a "year of recovery" for the motor industry, adding: "Economic conditions remain extremely challenging, but industry expects demand to strengthen in the second half of the year.
"Competition in the retail sector will intensify as the industry seeks to re-balance demand across its new and used car and service and repair business. UK motor manufacturing recovered particularly well in 2010 and the outlook is for further steady growth this year."
Car sales fell by 18 per cent in December compared with the same month in 2009 to 123,817, with the market just below expectations. The best-selling car last month was the Vauxhall Astra although the Ford Fiesta was the top-selling model for the whole of 2010, with sales of more than 100,000.
More than 100,000 cars were sold through the scrappage scheme last year, around 5 per cent of the total.
The SMMT pointed out that, although car sales were up by 1.8 per cent last year, the 2010 market was still the second lowest in the past decade and almost 375,000 down on the 2007 figure.
Private car sales fell below a million in 2010 for only the second time in the past decade, dropping by 5.6 per cent over the year and by 37.5 per cent in December. Fleet sales were more resilient, growing by 10.3 per cent over the full year, while business demand also rose in 2010, jumping by 42.8 per cent in December.
The SMMT said fleet volumes are expected to sustain the market this year while private car sales are set to fall further, partly as a continuing effect of the end of the scrappage scheme.
Sales of UK-built cars increased by 17.4 per cent over the year and by 7.4 per cent last month, while sales of diesel models rose to a record 46.1 per cent following a slowdown in demand for petrol vehicles post scrappage.
The Ford Fiesta was the best-selling new car for the second successive year.
The top-selling models for 2010 were:
1. Ford Fiesta - 103,013
2. Vauxhall Astra - 80,646
3. Ford Focus - 77,804
4. Vauxhall Corsa - 77,398
5. VW Golf - 58,116
6. VW Polo - 45,517
7. Peugeot 207 - 42,185
8. BMW 3 Series - 42,020
9. Mini - 41,883
10. Nissan Qashqai - 39,048
