Could you get a good enough one for £3000? How do you waterproof it? I thought - small - medium sized (Renault Vivaro), but not a Renault as I heard engines are bad. Where's the best place? Auto Trader or a dealer? I heard you need to check the suspension as previous tradesmen owners might have knackered it. And it's best to avoid previous owners who were brickies or roofers and were carrying heavy loads!
