So new automatically means economical ? Some of the most economical cars around are old. I used to have a Diesel Citroen AX. It would regularly put back 100mpg and i sold it for £200 7 months ago. If you want my advise buy a mid 80's diesel. Then you get Cheap Tax, Cheap Insurance and Cheap Motoring! Edit- After a small bit of Research. - "In 1989 a naturally aspirated diesel AX, using the 1360 cc all aluminium alloy TUD engine, managed a figure of 2.7 L/100 km (87 mpg–U.S. / 105 mpg–imp), totalling over 1,000 miles (1,609 km) from Dover to Barcelona. This was the longest ever distance travelled on 10 imp gal (45.5 L/12.0 US gal) of fuel and earned it a place in the Guinness Book of Records as the most economical production car." Another edit after a bit of maths ! SHIT...Just realised thats 1000miles on £54.60 ,if you put diesel at £1.20 a litre as it is at my local Sainsbury's !
