Oil stocks, car makers weigh on European shares

* FTSEurofirst down 1.6 percent

* Oils, car makers weigh on benchmark index

* Market players hope for aggressive interest rate cuts

FRANKFURT, Dec 3 (Reuters) - Oil and auto shares depressed European stocks by midday on Wednesday while a slew of negative economic data boosted hopes for aggressive interest rate cuts in Europe and Britain this week.

At 1156 GMT, the pan-European FTSEurofirst 300 index .FTEU3 was down 1.6 percent at 812.44 points, having risen 1.8 percent the day before.

Oil shares were the biggest losers on the index, as crude oil CLc1 continued to hover around $47 a barrel after falling 5 percent in the previous session. BP (BP.L), Royal Dutch Shell (RDSa.L) and Total (TOTF.PA) slid between 2.8 and 4.7 percent.

Car makers took a whipping after their U.S. peers GM (GM.N), Chrysler and Ford Motor Co (F.N) posted a drop in combined U.S. sales of nearly 40 percent for November.

In addition, the VDA association of German carmakers said it saw more trouble ahead as the market shrinks further next year [ID:nL3119780]. Daimler (DAIGn.DE), BMW (BMWG.DE) and Peugeot (PEUP.PA) were down between 3.5 and 4.2 percent.

Euro zone services activity fell further than initially thought in November to a record low while inflationary pressures continued to subside, a key survey showed.

In addition, Euro zone retail sales fell much more than expected in October, underlining weak consumer demand.

But analysts said bad news was mostly priced in and was unlikely to influence rate decisions further.

"We know the data flow, it is already been factored in, it is the reaction now that counts almost more than the data itself," said Dresdner Kleinwort strategist Philip Isherwood.

"The expectation is tomorrow to see hopefully some monetary reaction ... with the European Central Bank decision. The market is looking for 75 basis points, but there is the feeling they will only get 50 basis points, which is mildly disappointing."

A Reuters poll of economists last week [ID:nLP658955] pointed to the ECB cutting rates by a relatively conservative 50 basis points to 2.75 percent.
