If you want to buy a Laguna for £4k, buy one for £1k and then spend £3k on it inside the first 12 months, and every 12 months thereafter!
Shame, as when they were new, they were very nice cars to drive. But used they make less sense than burning the £20 notes you’d use to buy it on a bonfire! Even forgetting the engine problems, you’ve got the most unreliable electrics in any car ever and suspension that needs replacing every few years.
PeterPoddy has a point about manuals and in particular, petrol cars. Problem is the price of fuel these days, average milage for most people and an average petrol is going to cost £1k more per year in fuel than the average diesel!
£4k on an estate car…? Hmmm… Sadly gotta be a VW/Audi/Skoda to be honest! And even then they won’t be without their faults, just that at least VAG faults will be cheaper to fix in general (on a diesel engine) than on a Renault or a Ford.
