They are both 1.5 diesels, well they do come standard with half leather seats any way, yeah it has got the Tom Tom, electronic climate control, traction control switch, sunroof, iPod connectivity, folding wingmirrors, start stop button. The full leather option is abit pricey and you dont really get that much more leather to be honest. The blue one is pretty much basic as it doenst have Tom Tom or iPod connectivity just a line in jack, my brother likes to think it's the stripped out tracked version cause it doesn't have all toys in, yeah I really like the silver it's hard to find pictures for them so they can't be that many kicking around, I like the Malta blue just too popular for me, had it for 24 hours now and I'm completely in love with it, We both went to a cruise tonight in memorial for a drag racer who recently died in a race, and even though they didn't really fit in the scene we got plenty of questions and looks, so overall I'm really pleased, thanks for the nice comments
