a 207 can be had for about 2500/2600 now, through amcap or a dealer willing to match the price.
i can supply one through my work also.

would there be legality issues with going down to a 2.0 litre from a 2.5 though? as the blocks are stamped ej20 not ej25 which is what is on the plates.

Also i have found that warranty is getting alot stricter on cars with modifications that come through work.
