Pros
remaps are cheap and for £300 you should get an extra 35 - 45 bhp if you want more power then you need to spend a few quid.
driving in the wet is fun !!!
keep the oem 17" wheels if you can, the car will handle a little better
Cons
OEM rear spring prone to snapping
Roof Rails bubble from corrosion beneath the paint really common
lower front doors rust
aerial mount
CTS - will need replacing and thermostat
softtouch paint peeling on buttons and switches
pixels on DIS
An RNS-E upgrade with bluetooth is well worth the effort to update the cars interior and retro fit the Recaros if you dont have them already
