Seeing nothing on the inside is not a true gauge of what is lurking behind.

My car looked pristine on the inside of the car but even though they had removed the old outer sills there was rust lurking at the bottom where moisture had pooled and also further up the inner sill.

Now this could have lasted for some time without doubt but if the rest of the car is immaculate then why have a temporary repair panel fitted instead of the correct short sill which I have previously mentioned give the correct strength profile

it's gone in to have them done. Wish me luck.

I've got the chance to buy a 1275 gt which on the face of it is mint condition and the bottom of car has been painted the same as the main body, the car however has had over sills fitted. The seller gave me previous owners number and I phone him and told me he did full body respray and any repairs to metalwork undertaken,
I've told the seller I'm not happy that there are over sills fitted and as I don't know what is lurking under them I would want to pay at least £2-3k below asking price.
Am I absolutely off my rocker?! Of interest I can't see any major repairs to footwell or crossmember which makes me think the car is solid. Is there any other way I can check?

If the work was undertaken properly and recently with all rust having been removed, then it might well be ok.

 

Remember, some people fit coversills because they believe they are better than the correct narrow sills so it could just be a case of carefully removing the cover sills, cleaning up where required and then fit the correct ones.

 

BUT, you really need to be sure that it's all good behind because if it has been hanging on to moisture for some time, then you could well be looking at replacing the inner sill and the heelboard too.

 

This one looked ok

But wasn't.

And i don't think it had been on there very long either...

 

I ended up fitting a new inner sill, heelboard and repairing the lower flitch to put it right

absolutely. You wouldn't have known from the outside mind. Glad to get some solid metal back on the car.

I would say that if over sills are the ONLY problem and it can be proved that they have not been on for long, the price of any Mini should be reduced by about £600 to £1000 to allow for their immediate replacement.

But their presence would make me look far more closely than usual at every other area that can be bodged. Definitely need carpets and rear bin bottom liners out, to get a better view.

What do you fellas think about these sills? On a '69 Cooper S , probably for a very long time. Flakey and crunchie through the jacking point but the floor is not a total disaster area at all. Should I just rip the so and sos off and replace with m machine panels? The car won't be going out in the wet and stored in a dry, well vented garage.

Err this is a no brainer, remove and repair. Your car is too valuable to have Oversills on.
