Car Specs - website?

[Rob2005uk]

Is anyone aware of a website where you can compare car specs? Obviously for the newest cars you can download brochures from the manufacturer websites but is there a website where you can view older specifications to find out if a particular feature is on a particular trimline?

I know on autotrader specs are listed but I've often found these to be incorrect.

Thanks

Parkers has this feature (at least it used to, not checked recently).
