My old girl has a t reg ford galaxy 2.3 petrol. Great car and shed loads of space. I've had many a car parts in the back too inc a frst boot and bonnet and both bumpers in one go before no problem.

Ours is a mk1 galaxy but if you want something a bit up to date the mk2's are great inside I looked at one and every seat had double armrest and felt like a sofa to sit in

As for fuel economy I got all the way from Watford to Oban Scotland on a single tank of juice

Steer clear of the 2.8 v6s though as they cane fuel

They also done the mk1 in a si model which has rear upper spoiler,side skirts and a front bumper splitter too which makes them look a lot nicer

Hope this helps
