The choice of engine depends on how many miles you do and if you can recoup the extra outlay in a reasonable time.Saying that the Diesel will have a lot more pulling power (torque) than the 1.6.I have the 1.6 and I average about 36mpg which isn't too bad really.As for colour Wicked Red is nice if you can put up with the Postman Pat jokes,I also liked Rainforest Green but again the family weren't keen,Med Blue is not too bad but it stands out a bit and would get on my nerves after a while.Just make sure you get AIR-CON :blink: As for dealers the Luton Citroen Centre are the best i've found http://www.lutoncitroen.co.uk/ They've got an '04 Silver Desire at the mo for £7995 no air-con though :)
