Renault Laguna III - 2.0dCI Sport Tourer Owner's Review - Gromit
Subaru 2.0 and 2.5 H4 boxer engines are cambelt, 60,000 mile change interval. Both good for 28-30 mpg driven sensibly (cough cough). 4 speed autos quoted 1-2mpg more economical than manuals.
3.0 and 3.6 H6 are chain cam, 5 speed auto only, and sub 25mpg.
Edit: If you get that 2.5 auto Outback, there's no way you'll want to leave it sitting on the drive to take a diesel Golf instead. I have to make myself drive the Panda instead of the Legacy every morning too :-(
