We have four children and are struggling with our Citroen C4 Grand Picasso. We need a secondhand replacement with space and a decent boot, so very few cars are suitable. We do 6000 miles per year with many local journeys. Modern diesels are not ideal, but petrol variants are rare and thirsty for this size of vehicle unless converted to LPG. We've ruled out a number of vehicles, for a number of reasons. So we've narrowed it down to a Ford Tourneo Custom or a Hyundai i800. We just drove a Ford Tourneo Custom LWB L2 15-plate, 125PS nine-seater on 47,000 miles. It's an ex-taxi, so not perfect, but comes from a Ford dealer with one year warranty. The engine is adequate, but frustratingly gutless below 2000rpm - though we'd get about 35mpg. There are also various reports about gearbox failures and Transits being more prone to issues with DPFs. We have our eyes on a Hyundai i800 17-plate with 9000 miles and 4.5 years warranty remaining. It's a nice size vehicle with eight seats, and it looks and feels more car-like than the Tourneo. We anticipate 28mpg, but at 6000 miles per year, this is an £150 extra per year, with the added benefit of no DMF (Dual Mass Flywheel) to fail. Please could I draw on your expertise? Do you have any thoughts on reliability, faults, running costs, performance, comfort, parking, depreciation etc?
