usuall things that get checked
*Your brakelights need to work and if it's raining, your windscreen wipers need to work.
*Your car cannot have any fluid leaks at all.
*seatbelts in good cond
*brake pedal feels solid
*engine bay in good cond/everythiung secure
*tyres can't be bald
*make sure there is nothing loose in the car (boot/cabin)
*remove your space saver on the day (make sure it's still in the car on the way there.. you may need it )
Sounds like your car would be fine to pass though. Chris (Evil_Weevil and D_I_F will be doing the scrscruteneer checks on the day, so shoot one of them a PM or they can answer in here if they see this
Do you have any major exhaust mods, or do you have battery/oil/fuel relocated ?? this obviously needs to be done properly and enclosed where needed etc..
